Darwin xz flag fix

The gzip flag z was being passed to tar on Mac OS for decompression of xz archives. This fixes #119 (closed).
I took the liberty to include a commit that drops dashes from the flags passed to tar for other cases, rationale being it only increases compatibility. If anyone objects I can easily drop or revert that commit.

This is good. https://pubs.opengroup.org/onlinepubs/007908799/xcu/tar.html ghcup is POSIX sh and POSIX doesn't specify leading dash afais.
