Closes https://github.com/acidanthera/bugtracker/issues/2281

 - memtest86 does not re-read the text mode size after changing GOP resolution.
 - Possibly this is an issue in OC, in that this should not normally change? (But it is
   fundamental to Builtin renderer handling of console resolution that it will change,
   unless a fixed user mode size is specified.)
 - The only effect of this in memtest86 is that it attempts to place the white footer
   line of its text UI below the bottom of the screen; so this clamping, which seems
   reasonable anyway, completely works round it.
