            [Fedora 45 Change] Add dependency on shared ODBC driver registration subpackage

Add 'Requires: odbcinst-generate' so the drop-in snippet mechanism
works on iODBC-only hosts.

The 'odbcinst-generate' subpackage (from unixODBC SRPM) provides:
- 'odbcinst-generate' script that assembles '/etc/odbcinst.ini' from
  per-driver drop-in snippets
- RPM file triggers that regenerate the config when drivers are
  installed or removed
- Drop-in directories ('/usr/lib/odbc/odbcinst.d/',
  '/etc/odbc/odbcinst.d/')

The subpackage is named driver-manager-neutral ('odbcinst-generate',
not 'unixODBC-odbcinst-generate') because both unixODBC and iODBC
are equal consumers.

With this dependency, installing 'libiodbc' (even without 'unixODBC')
ensures that ODBC driver registration via drop-in snippets works
correctly.  Since iODBC requires absolute paths for dlopen(),
'odbcinst-generate' resolves bare library names in snippets to
absolute, architecture-correct paths in the generated config.

iODBC multilib limitation:
- iODBC does not support the 'Driver64' key that unixODBC uses for
  multilib — its driver loading code ('_iodbcdm_driverload()' in
  'iodbc/connect.c') reads only 'Driver', and its dlopen wrapper
  ('DLL_OPEN' macro in 'iodbcinst/dlf.h') calls 'dlopen()' directly
  with no multilib awareness or search-path fallback
- On multilib systems, 'odbcinst-generate' emits both
  'Driver = /usr/lib/odbc/...' and 'Driver64 = /usr/lib64/odbc/...';
  iODBC sees only 'Driver' (the 32-bit path) and silently ignores
  the unknown 'Driver64' key
- This means iODBC always loads the 32-bit driver on multilib hosts,
  which is correct for iODBC's typical use case (32-bit applications)
