5b12071ba0 Remove WaitForSanitizers from ptrace monitor & add to global forkserver
This makes should ensure global forkserver will be single threaded before forking the sandboxees as it does not go through WaitAndFork.

Waiting for sanitizers is not needed in the monitor and should reduce latency
by 1 second for all sanitizer builds. Currently it'll always wait up to 1 seconds for the process to become single-threaded, which will never happen as monitor itself is running in a separate thread.
