bitbake: lib/bb/utils: prevent movefile from changing dest dir permissions

Prevent movefile from falsely setting the source file's owner and
permissions on the destination directory instead of the destination
file when moving between devices.

This bug caused the last file moved into a directory to dictate the
directory's owner and permissions.
