Image caches: allow overriding cache dir

Browse Source 
Images were being cached in /tmp, with no option to
override. Now $PODMAN_TEST_IMAGE_CACHE_DIR can be
used to point to a user-preferred location. If unset,
try $TMPDIR before settling on /tmp.

Also: refactor the logic for determining the tarball name.
Also: include registry name in tarball name.
Also: clean up unused/unnecessary code
Also: do not echo "Restoring..." if we're not actually restoring.
