Clean up remaining headers that are specific to liblockdep but lived in
the shared header directory.  These are all unused after the liblockdep
code was removed in commit 7246f4dcaccc ("tools/lib/lockdep: drop
liblockdep").

Note that there are still headers that were originally created for
liblockdep, that still have liblockdep references, but they are used by
other tools/ code at this point.
