virtiofsd: Remove fuse_req_getgroups

Remove fuse_req_getgroups that's unused in virtiofsd; it came in
from libfuse but we don't actually use it.  It was called from
fuse_getgroups which we previously removed (but had left it's header
in).

Coverity had complained about null termination in it, but removing
it is the easiest answer.

Fixes: Coverity CID: 1413117 (String not null terminated)
