Miroslav Lichvar aa4bf41400 privops: use SOCK_SEQPACKET sockets when supported ...

SOCK_SEQPACKET is preferred over SOCK_DGRAM for communication with the
helper as the process will get an error when the other end of the socket
is closed. It's not supported on all platforms.

If SOCK_SEQPACKET is defined, try creating the pair of sockets with this
type first and if that fails, fall back to SOCK_DGRAM.
