[PATCH] tests/functional: Enforce sha256 as hashsum algorithm for all tests

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

The functional testing framework currently supports both, sha256
and sha512 as hashsums for the assets. However, all but one test
currently only use sha256, which should also be sufficient according
to the current security standards. Having two algorithms around already
caused some confusion (e.g. the clean_functional_cache.py script only
supports sha256 right now), so standardize now on enforcing sha256
before more tests use a mix of the two algorithms.
