Add ->flock() operation to low and high level interfaces
This fixes problems with emulating flock() with POSIX locking.
Reported by Sebastian Pipping.
As with lock/setlk/getlk most filesystems don't need to implement
this, as the kernel takes care of file locking. The only reason to
implement locking operations is for network filesystems which want
file locking to work between clients.
