Kill on each iteration of graceful exit loop

I believe it's possible for the `main_pid` to disappear between `kill` and `sigtimedwait` by means of an `exec` from a multithreaded process (`PTRACE_EVENT_EXIT` happens after the `exec`ing thread changes its tid to main_pid)

Adding AllowOpen to AllowLlvmSanitizers to avoid having to add AllowOpen in addition when it's only needed for running under the sanitizers.
...
In cases where SAPI users overwrite the default policy instead of extending it, the sandbox will fail with an `openat` violation. This is automatically inherited in the default policy.
The advantage with this implementation is that we don't expose the open* syscalls when not running under the sanitizers.

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.
