ci(gitea): broaden libclang find pattern to match versioned sonames

Second LIBCLANG_PATH failure mode: my 'libclang.so.*' with -type f
pattern returned nothing because Debian Bookworm's runtime library is
'libclang-14.so.1' (versioned, with no plain libclang.so.* symlink),
and the .so symlink is itself a symlink not a regular file (-type f
excludes it).

bindgen accepts any of: libclang.so, libclang-*.so, libclang.so.*,
libclang-*.so.* — so the broader 'libclang*.so*' (no -type filter)
catches every variant. Also broadened search root from /usr/lib to
/usr to cover both /usr/lib/x86_64-linux-gnu/ (runtime lib) and
/usr/lib/llvm-*/lib/ (dev symlink).

Log line now includes the actual matched path so future debugging
is one glance.
