Subject: Tweaks for sigqueue tests: - slightly adjust code for style, sort
 headers. - in sigqtest2, print received signals, to make it easy to see why
 test   failed. - in sigqtest2, job_control_test(), cover a race by adding
 sleep after   child stopped itself to allow for SIGCHLD due to stop and exit
 to not   be coalesced.

MFC after:	2 weeks
