Ian Wienand b25d0337b8 Move to a common lock-file directory
In a couple of places we use flock for critical sections, but we leave
lockfiles around in various locations which can be confusing.

Introduce DIB_LOCKFILES global (under ~/.cache/dib/lockfiles) and
write lockfiles in there.

Fix up removal of the lockfile in the yum path; we just want to make
sure we cleanup the .rpmmacros file, but we don't need to remove the
lockfile as well.
