Fixes #19928. This commit changes the behavior of tar_options so that anything
without a - to start gets appended to the "x" for extraction (e.g. "z" or "J")
but anything that starts with a - properly gets appended as an explicit
argument. In addition, filename no longer needs quoting since it's an
array-based argument now.
