System tests: cleanup, and remove obsolete skips

* 070-build:
  - remove workaround for #9567, which is closed.
  - add many more cases to the ignorefile test,
    to test complicated special cases of Buildah PR 3486.

* 160-volumes:
  - remove a skip_if_remote, volumes now work on remote
  - use a random name for tarball, and clean up when
    done using it. This fixes a gating-test failure
    (test runs as root, then rootless, and rootless
    can't clobber root's file).
