Kernel: Fix behaviour of PT_TRACEME in ptrace
The behaviour of the PT_TRACEME feature has been broken for some time,
this change fixes it.
When this ptrace flag is used, the traced process should be paused
before exiting execve.
We previously were sending the SIGSTOP signal at a stage where
interrupts are disabled, and the traced process continued executing
normally, without pausing and waiting for the tracer.
This change fixes it.
