cloexec: set FD_CLOEXEC for all full duplex pipes

All users of full duplex pipes enable FD_CLOEXEC later anyway so let's
just do it as part of _dbus_full_duplex_pipe. By side effect this allows
to make use of SOCK_CLOEXEC which fixes a race when forking/execing from
a different thread at the same time as we ar in this function.
