During Debian packaging, the cache path related tests raise failures.
Test failures were raised by: * test_no_write_permission_to_cache * test_can_open_read_only_cache
Both tests use a path generated by `Help.cache_path()` (from `test_helper.rb`) during test, which could be differ with a real path generated by Bootsnap C extension. During the test, the cache paths generated by Bootsnap C extension comes randomly.
At this time, this issue was raised only on the Debian packaging environment (dpkg-buildpackage, sbuild, pbuilder, ...). Previous versions in Debian also have this issue, but there was no bug reported on the Debian BTS (and also on the upstream issue tracker).
So I'll skip the tests at this time. This bug was reported to upstream.
This patch will skip the tests related to cache path.
