[PATCH 1/5] check-parallel: adjust concurrency according to CPU count

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

COncurrency is currently hard coded at 64 worker threads. THis is
too many for small CPU count machines; the idea is to create a
sustained load of roughly one test per CPU as they are mostly single
threaded/single process tests. The number "64" was chosen because
I've been developing this functionality on a 64p VM.

Rather than hard coding the concurrency, probe the number of CPUs
available and create that many running contexts.
