mapfile: fix locking.

The current locking uses lockf, and is completely broken.
When you hold a lockf lock, any close of any fd on that file will
release the lock.  So map_read() call which is made as soon as we get
the lock, will immediately drop the lock.

So change to flock locking which isn't so badly designed.
