[mythtv] mythgame segmentation fault when mythgame binary is defined

[Michael Kedl]

I am using the SDL version of xmame.

I had to comment out the screenshot dir lines in mamehandler.cpp I
think.

And use version 1.6 of main.cpp.

and then it worked fine.

The screenshot stuff is probably related to SDL version.

Not sure what those few 1.6 vs 1.7 changes did.  Maybe moved the
mythgame db stuff to the backend?  which for me is on another machine.
