Remove unnecessary usages of BLocker::Sem().

Most of these should have been BLocker::InitCheck() anyway.
The one that was actually using the sem (MessageLooper)
should just store the name parameter, which simplifies
things anyway.

Done as a result of a branch where I'm experimenting
with making BLocker not even create a semaphore in
"benaphore" mode.
