[PATCH 1/4] src/t_rename_overwrite: fsync to flush the rename operation result

[Zorro Lang <zlang@redhat.com>]

The generic/035 fails on glusterfs due to glusterfs (or others like
it), the file state can't be updated in time in client side, there's
time delay. So call fsync to get the right file state after rename.
