main: drop code to handle flock 
the implementation of flock(2) was wrong and it caused a deadlock when
multiple processes tried to lock the same file.

Drop it and let FUSE handle locking for us.

main: skip ENOTDIR in a lookup 
if we are looking for a path in a lower component, skip ENOTDIR as a
component might be a whiteout.

This happens only when running as root, as the whiteout takes the same
name of the deleted file/directory.
