Add lockmgr(9) probes to the lockstat DTrace provider.

They follow the conventions set by rw and sx lock probes.  There is
an additional lockstat:::lockmgr-disown probe.

Update lockstat(1) to report on contention and hold events for
lockmgr locks.  Document the new probes in dtrace_lockstat.4, and
deduplicate some of the existing probe descriptions.
