package/libglib2: bump version to 2.76.1

- glib2 has moved from PCRE to PCRE2 [1].
- Drop `fam` option since it no longer available [2].
- Drop "0001-fix-compile-time-atomic-detection.patch" since upstream
   patch was dropped and new atomic detection implementation has been
   applied in this version.
- Drop "0002-remove-cpp-requirement.patch" since upstream has modified
   its Meson scripts to have any C++ usage as optional.
- Drop "0003-Add-Wno-format-nonliteral-to-compiler-arguments.patch"
   since change is available in this version.
- Add new patch to address new Werror compilation errors [3].
- Renamed "0004-*.patch" -> "0001-*.patch" since it should still be
   applicable for its mentioned build case.
