Luca Boccassi 80d523dcc8 DBusCredentials: add support for PID FDs via SO_PEERPIDFD 
The new socket option SO_PEERPIDFD allows to pin the process on the
other side of the socket by file descriptor, which closes a race
condition where a PID can be reused before we can pin it manually.
Available since Linux v6.5.

When storing credentials, pin the process by FD from the PID.
When querying the PID, if the PID FD is available, resolve
it from there first if possible.

Ensure the DBusCredentials object only returns the PID FD if it was
obtained by this call, so that we know for sure we can rely on it
being safe against PID reuse attacks.
