            Fix SPDX license tag: 'LicenseRef-Callaway-LGPLv2' -> 'LGPL-2.1-only AND GPL-3.0-or-later'

License analysis of all source files (196 total, 161 with headers):

LGPL-2.1-only (libraries: libIL, libILU, libILUT):
- 'COPYING' contains the full text of "GNU Lesser General Public
  License, Version 2.1, February 1999" (the "Lesser" variant, not
  the older "Library" GPL 2.0)
- 'README' states: "DevIL is an Open Source image library whose
  distribution is done under the terms of the GNU LGPL license.
  See the COPYING file for more details."
- Core source files under 'src-IL/', 'src-ILU/', and 'src-ILUT/'
  carry copyright headers (e.g. "Copyright (C) 2000-2009 by Denton
  Woods") but no per-file LGPL license grant
- No library source file contains "or (at your option) any later
  version" in a project license grant context
- The PowerBASIC examples ('projects/powerbasic/') reference "GNU
  Lesser General Public License" via URL without specifying a version
  or "or later" clause
- The old Fedora tag 'LGPLv2' (without +) correctly indicated no
  "or later" option

GPL-3.0-or-later ('ilur' binary):
- 'src-ILU/ilur/ilur.c' explicitly states: "This program (ilur) is
  free software: you can redistribute it and/or modify it under the
  terms of the GNU General Public License as published by the Free
  Software Foundation, either version 3 of the License, or (at your
  option) any later version."
- The 'ilur' binary is shipped in '%{_bindir}/ilur' in the main
  package, so GPL-3.0-or-later must be included in the License tag
- 'test/format_test/testil.c' also carries GPL-3.0-or-later, but
  test files are not shipped in any binary RPM

Excluded / dead code (not affecting the License tag):
- 'src-IL/src/il_wdp.c': explicitly "not under the LGPL license,
  unlike the rest of DevIL" but compiled out via '#define IL_NO_WDP'
  (always set by configure)
- 'src-ILU/src/ilu_scaling.c': Public Domain code by Dale Schumacher,
  but entirely inside '#if 0' / '#endif' (never compiled)
- 'src-ILU/src/ilu_filter_rcg.c': Public Domain notice for Dale
  Schumacher's code is inside a C comment block (commented out)
- 'projects/DotNet/': BSD-3-Clause code by Marco Mastropaolo, but
  DotNet bindings are not built or shipped by the Fedora package

Bundled permissive code compiled into libIL:
- 'src-IL/src/il_neuquant.c': NeuQuant algorithm by Anthony Dekker,
  1994 custom permissive license ("full and unrestricted irrevocable
  [...] right and license to deal in this software [...] with the
  only requirement being that this copyright notice remain intact").
  More permissive than LGPL; subsumed by LGPL-2.1-only in the
  combined binary.
- 'src-IL/src/il_gif.c': LZW code "based on code released to the
  public domain by Javier Arevalo" -- public domain, subsumed by
  LGPL-2.1-only in the combined binary.

Also remove the "Automatically converted" comment and bump release.
