[PATCH 4/5] sstate.bbclass: disable thread lock if we don't have events

["Jose Quaresma" <quaresma.jose@gmail.com>]

commit f2053844958325496a9387874a8f3182400b71ca
'classes/sstate.bbclass: Enable thread lock when checkstatus'
adds a thread lock to don't lose the events from multiple threads
that runs on the ThreadPool.

commit 1444b8a2ae226829e719d3d184fca27e5940ae0d
'sstate.bbclass: Only show sstate mirror progress bar for >= 100 objects'
disable the events if we don't have a minium number of objects.

So we can only use the thread lock when we have the events in place.
