Garbage collect mtxpool_lockbuilder, the mutex pool historically used
for lockmgr and sx interlocks, but unused since optimised versions of
those sleep locks were introduced. This will save a (quite) small
amount of memory in all kernel configurations. The sleep mutex pool is
retained as it is used for 'struct bio' and several other consumers.
Discussed with: jhb
