Remove lockfile configuration from frontend, make it job of libalpm

I previously introduced some patches to make just about every path in
pacman/libalpm configurable; doing this with the lockfile seemed a bit too
far and we really should just place the lockfile where it belongs- with the
DB that needs locking.
