remove rb_time_interval() and gettimeofday() dependency

This function isn't exported in the standard Ruby headers,
it returns an aggregate value and isn't available in Rubinius,
either, so nuke it.

While we're at it, use clock_gettime() instead of gettimeofday()
to avoid unnecessary timeval usage since mq_send/mq_receive
rely on higher-precision timespecs instead.
