Adapt the Phantom readypgm to the replica feature in the epu recipe

Program names are now suffixed by a unique number generated inside the
epu recipe. Make a partial match with grep instead of asking for an
exact match from supervisorctl.

Since there is generally only one program per supervisord, it shouldn't
change anything.
