            Fix SPDX license expression: add missing LGPL-2.1 variants

The 'src/st/croco/' library (~35 files) and many 'src/st/' widget files
are licensed under LGPL-2.1-only — they specify "version 2.1 of the
GNU Lesser General Public License" with no "or later" clause.

Another subset of 'src/st/' files (st-border-image.c, st-drawing-area.c,
st-focus-manager.c, st-shadow.c, st-theme-context.c, st-theme-node.c,
etc.) are LGPL-2.1-or-later — "either version 2.1 of the License, or
(at your option) any later version."

These are distinct from the LGPL-2.0-or-later files (menu-editor
scripts, 'cinnamon-secure-text-buffer.c') which reference the
"GNU Library General Public License" version 2.

Evidence:
- 'src/st/croco/cr-additional-sel.c': "version 2.1 of the GNU Lesser
  General Public License" (LGPL-2.1-only, no "or later")
- 'src/st/st-adjustment.c': "GNU Lesser General Public License,
  version 2.1" (LGPL-2.1-only)
- 'src/st/st-border-image.c': "GNU Lesser General Public License ...
  either version 2.1 ... or (at your option) any later version"
  (LGPL-2.1-or-later)
- 'files/usr/share/cinnamon/cinnamon-menu-editor/cme/MainWindow.py':
  "GNU Library General Public License" version 2+ (LGPL-2.0-or-later)
