Program hangs on full gc collect with --DRT-gcopt=f…" fixing this issue:

- fix Issue 22843 - Program hangs on full gc collect with --DRT-gcopt=fork:1 if
run under valgrind/callgrind

  the clone() call was using the `CLONE_CHILD_CLEARTID` flag without passing
   it a thread id pointer in the optional argument

  based on the comment `// child thread id not needed`, the flag was probably
   intended to disable any passing of a thread id which is already the
   default if neither of `CLONE_CHILD_CLEARTID` and `CLONE_CHILD_SETTID` are
   used, so just remove the flag
