This adds the pidfd_open() syscall.
pidfd_open() allows to retrieve file descriptors for a given pid. This
includes both file descriptors for processes and file descriptors for
threads.
I'm ok with the pidfd_open() call to just get a pidfd, but that
"pidfd_to_profs()" needs to go away.
If you want to open the /proc/<pid>/status file, then just do that.
This whole "do one and convert to the other" needs to die. No, no, no.
