[Piglit] [PATCH 2/2] framework: remove last use of core.checkDir

[Dylan Baker]

This function has two problems:
1) It desperately needs to be refactored to make better use of
   the except block.
3) It needs to be refactored to raise a PiglitFatalException.
2) It's far too specific to be in core, it really should be refactored
   to raise a PiglitInternalError when failifexists and exists are true

While we could invest this work, it only has one consumer, and it would
be far easier to just remove the function and put the necessary code
directly in the only place it's used.

That's what this patch does.
