Increase WSGI process count to 5 on 64bit

Increase the WSGI daemon worker process count from 2 processes to 5
processes. This allows IPA RPC to handle more parallel requests. The
additional processes increase memory consumption by approximante 250 MB
in total.

Since memory is scarce on 32bit platforms, only 64bit platforms are
bumped to 5 workers.
