[Piglit] [PATCH 1/3] util/waffle: Print message when falling back to compatibility context

[Chad Versace]

Some tests declare in their config block that they support running under
both core and compatibility contexts. In this case, Piglit first attempts
to use a core context; if core context creation fails, then Piglit falls
back to the compatibility context.

This patch prints a diagnostic when the fallback occurs.
