Tighten gdb.threads/no-unwaited-for-left.exp regexps
A WIP version of a patch
(https://sourceware.org/pipermail/gdb-patches/2022-June/190202.html)
resulted in a bug that went unnoticed by the testuite, like so:
(gdb) PASS: gdb.threads/no-unwaited-for-left.exp: enable scheduler-locking, for main thread
continue
Continuing.
[New Thread 1251861.1251861]
No unwaited-for children left.
(gdb) PASS: gdb.threads/no-unwaited-for-left.exp: continue stops when the main thread exits

4 Thread 1251861.1251861 "no-unwaited-for" <unavailable> in ?? ()
The current thread <Thread ID 1> has terminated. See `help thread'.
(gdb) PASS: gdb.threads/no-unwaited-for-left.exp: only thread 3 left, main thread terminated
Somehow, above, GDB re-added the zombie leader back before printing
"No unwaited-for children left.". The "only thread 3 left, main
thread terminated" test should have caught this, but didn't. That is
because the test's regexp has a ".*" after the part that matches
thread 3. This commit tightens that regexp to catch such a bug. It
also tightens the "only main thread left, thread 2 terminated" test's
regexp in the same way.
