giflib: add version check override

The giflib-utils executables (gif2rgb, gifbuild, gifclrmp, giffix,
giftext, giftool) do not report the package version when run, which
causes the generic version probe to fail.

Add a test-version.sh to skip the version check for the giflib and
giflib-utils packages.
