perf lock: Fix and add misc documentally things
I've forgot to add 'perf lock' line to command-list.txt,
so users of perf could not find perf lock when they type 'perf'.
Fixing command-list.txt requires document
(tools/perf/Documentation/perf-lock.txt).
But perf lock is too much "under construction" to write a
stable document, so this is something like pseudo document for now.
And I wrote description of perf lock at help section of
CONFIG_LOCK_STAT, this will navigate users of lock trace events.
