Add fix for gcc bug

The following error flaws the check for gid in the group_info struct. For now
we just set the corresponding define manually.

/var/lib/dkms/openafs/1.6.20.2/build/conftest.dir/conftest.c:43:8: internal compiler error: Segmentation fault
 struct group_info _test; printk("%x\n", &_test.gid);
        ^~~~~~~~~~
