mu7d: invert the order of execution of epg & u7d. This is important on

WIN32. If the console is closed while a client is watching a stream,
if the last executed process is u7d, that's the one Windows kills, and
it cannot do its cleanup. For the client to not get hung when the
stream is not closed properly (like Kodi does), by launching epg last,
we make sure u7d is closed properly and it can close all the streams
before exiting.
