oeqa/core/runner: Append PID in the test result folder name

It was found a case (see the bugzilla entry) where two runners were running at the same
second, creating identical test result folders, so one of them (the second runner)
was not able to create the folder because the other has already created it,
raising the following exception (many text was removed from log)

NOTE: Executing RunQueue Tasks
NOTE: Running task 1 of 2 (/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-mips/build/meta/recipes-core/images/core-image-minimal.bb:do_testsdkext)
