sysquota: we need to list nfs4 as a separate fs name for the sys_get_nfs_quota backend

at least the Linux kernel up to 3.5.0 lists NFSv4 aѕ nfs4 and not as nfs
(cherry picked from commit a6df44b3ae1ca6395d05e1af804a779d785358db)

Fix bug #9144 - nfs quota support not working with Linux nfs4 mounts.
