[PATCH 2/2] Temporarily delete old-style lock files

[Sebastian Spaeth]

The previous locking system would leave around lock files forever. This
commit attempts to delete those. We should include it for one release or
so and then remove it after some time.

This patch would clean up left-over lock files from the previous locking
system. It is purely optional and I leave it at the discretion of our
maintainer to decide whether we want to carry this patch for one release
before pulling it out again for good. Cleaning up ununsed stuff from old
versions is good, I guess.
