8284165: Add pid to process reaper thread name

[tstuefe]

Not a clean backport. ProcessReaperCCL.java (a test that tests that reaper threads have a null ContextClassLoader) does not exist in 11. I omitted that hunk.

Tests: I manually tested linux-x64 and verified that reaper threads now have the pid in their name.
