sched/pthread: return ESRCH when thread not found at pthread_detach

Browse Source 
https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_detach.html

If an implementation detects that the value specified by the thread argument
to pthread_detach() does not refer to a joinable thread, it is recommended
that the function should fail and report an [EINVAL] error.

If an implementation detects use of a thread ID after the end of its lifetime,
it is recommended that the function should fail and report an [ESRCH] error.
