[OE-core] [PATCH v3] 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>

Run in parallel the (oe)selftests using GNU/Parallel: for each test
defined, a job will be launched and at any time at maximum of jobs
will be executing (defaults to 4).

1. Run all modules

    parallel-oe-selftest.sh

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

    parallel-oe-selftest.sh wic bblayers

Signed-off-by: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Changes from v3 (both suggested by Andre McCurdy):
* fix typos in commit message and comments on code
* fix if condition on all-tests execution
