Remove Immediate XFB from DTM header

7f0834c, which added the Immediate DTM setting, also added a byte
to DTM headers for Immediate DTM. There are two problems with this:

1. The byte was added in the middle of the header, throwing off the
   offsets of several other settings. There are programs other than
   Dolphin itself that parse DTM files, so this is not acceptable.

2. If I'm not mistaken, Immediate XFB doesn't affect sync. Putting
   it in the DTM header unnecessarily prevents people from using
   a different value for that setting than what the movie author used.
