gluster/uss: change ctime attr of a dir when USS enabled

Consider a testcase:
 mount -t nfs host1:/vol1 /mnt
 ls /mnt
 ls /mnt/.snaps (As expected this fails)
 gluster volume set vol1 features.uss enable

Now `ls /mnt/.snaps` should work, but fails with No such file or
directory.
This is because NFS client  and Kernel VFS caches the list of files in a
directory.
This cache is updated if there are any changes in the directory attributes.

This patch solves the problem by changing ctime attribute when USS is
enabled
