tests: actually use bzip for test tarball

I inadvertently gzipped it last night. That in itself doesn't cause any
tests to fail because the download strategy code is robust, but it's
fixed here anyway to be consistent. Basically, I'm dumb.

I also took the opportunity to remove the other resource fork file, so
the tarball is clean.
