Abdessamad Derraz 057fd2d0f6 fix: isolate every test module however it runs
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.

"""A destination two systems declare with two hashes ships one file.
RetroDECK declares bios/disk.rom for pc88 (the N88SUB ROM) and for coco (the
CoCo disk ROM), and bios/cdibios.zip for two components with two md5. The
pack holds one file per path, but verify resolved each declaration to its own
file and counted both OK, so three green tools described a pack whose
frontend hashes bios/disk.rom for xroar and finds the PC-88 ROM.
