Mach ports used for IPC on Darwin should use MPO_CONNECTION_PORT when
available

Reviewed by Per Arne Vollan.
Previously, regular port types were created, which had no restrictions. The
receive rights should be created with `mach_port_construct` and the
`MPO_CONNECTION_PORT` and `MPO_IMMOVABLE_RECEIVE` options (if available)
so that the resulting ports are immovable.
