Series Acceptance Tests: update assets location and cancel tests if missing | expand

Commit Message

Cleber Rosa Sept. 7, 2020, 4:20 a.m. UTC
Asset files used on the acceptance tests (kernel, initrd images)
unfortunately are not guaranteed to always be available at the same
location.

Let's cancel (kind of like a skip) the test, when the asset is
missing.  This should prevent false positives, when failure are not
caused by changes in QEMU itself.
