[Piglit] [PATCH 1/8] framework/tests: Add tests for recompressing results

[Dylan Baker]

These tests demonstrate a bug that hasn't yet been exposed to users, but
will be exposed if the json version is ever bumped.

The bug results in a compression suffix being added to a result file
that already has a compression suffix, even one with the same suffix.
