tests/__init__.py keeps a run offline, its scratch under tmp/ and its
installer cache its own, but only discover -s tests -t . imported it.
discover tests ran with RETROBIOS_OFFLINE unset, scratch on the /tmp
tmpfs and the user's real installer cache, the setting in which e2e
fixtures had written into the shared .cache/large. Every test module now
imports the package first, and a test fails on a module that does not.
test_verify_listing.py took its line with the previous commit.
LRPS2 reads pcsx2/resources/GameIndex.yaml through its data directory
and declares no file entry for it, so the truth entry other cores build
named armsx2 and yaps2 alone and hash_conflict missed LRPS2's copy. A
core whose data directory holds a file at an entry's path now folds in
as a reader with the cached copy's hashes, unless the profile lists what
it reads under that tree (yaps2, pcee2).
