tools/lib/lockdep: drop leftover liblockdep headers

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.
