Commit fb9edbe9 shortened held_lock->check from a 2-bit field
to a 1-bit field.

Make liblockdep compatible with the new definition by passing check=1
to lock_acquire() calls, rather than the old value check=2 (which
inadvertently disabled checks by overflowing to 0).

Without this fix, several of the test cases in liblockdep run_tests.sh
were failing.

These headers provide the same API as their pthread mutex
counterparts.

The design here is to allow to easily switch to liblockdep lock
validation just by adding a "liblockdep_" to pthread_mutex_*()
calls, which means that it's easy to integrate liblockdep into
existing codebases.
