    Teach 'tar' to support more file types

    In libarchive based (BSD) tar implementations, all file types can be
    uncompressed, even without a filetype letter.  In GNU tar's case
    "recent" versions (for over 10 years) can do the same.
    As such, remove the check for tar type and just assume it works.
