303 runs two test cases, one of which requires zstd support.
Unfortunately, given that this is not a unittest-style test, we cannot
easily skip that single case, and instead can only skip the whole test.

(Alternatively, we could split this test into a zlib and a zstd part,
but that seems excessive, given that this test is not in auto and thus
likely only run by developers who have zstd support compiled in.)
