    Cirrus-CI: Switch back to tzst packages, but use level 1
    
    We previously used `PKG_FORMAT: tar` to avoid spending a lot of time in
    zstd compression.  Instead just set PKG_LEVEL to compression level 1,
    which still produces packages that are much smaller than uncompressed
    tarballs with only a small penalty in build time.
