[PATCH 2/2] sstate: reuse the localdata copy on the mirror thread pool

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

We don't need a new copy of the bitbake data [localdata2] in each running
thread of the pool.

We can do the copy on the startup of the thread pool in each thread worker
and reuse it in each running thread, this is the same we did for the
connection_cache which is reused by fetcher.
