Christian Brauner e10899b2a0 net: add SO_PEERPIDFD_THREAD to get a thread-specific pidfd ...

SO_PEERPIDFD hands out a pidfd for the thread-group that called
connect() or socketpair(). Enable workloads such as the coredump server
or a broker to get a pidfd of the specific thread that connected to the
socket.
