mythtranscode: Avoid a floating point exception

Closes #10263

When mythtranscode is run with a non default profile it can
throw a flating point exception during initialisation:

Program terminated with signal 8, Arithmetic exception.

422	    if ((ydiff / display_video_rect.height()) < 0.05)
(gdb) bt
    new_display_visible_rect=..., new_aspectoverride=kAspect_Off, new_adjustfill=kAdjustFill_AutoDetect_DefaultHalf)

    framecontrol=false, jobID=-1, fifodir=..., fifo_info=false, deleteMap=...) at transcode.cpp:716

This is caused by display_video_rect.height() being 0.
