[OE-core] [PATCH v2 2/2] parallel-oe-selftest.sh: runs oe-selftest in parallel

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Parallelize oe-selftest execution using GNU/Parallel: for each test
defined, a job will be launched and at any time at maximun of jobs will
be executing (defaults to 4). Extra parameters can be given to
parallel cmd after double dashes ('--'). Some cmd line examples:

1. Run all modules

    parallel-oe-selftest.sh

2. Run certaing modules and print results in order (see parallel man page for
more info)

    echo wic bblayers | parallel-oe-selftest.sh -- --keep-order
