Switching from pargzip to pgzip showed much better efficiency over in apko, so let's do the same here to see if it frees up any resources during megabuilds. For smaller sections (control and signature), this just uses klauspost's gzip implementation instead of pgzip since don't need parallel compression for such tiny inputs. This will change the hashes of APKs because the compression will be different, but I don't believe we rely on reproducibility in melange. Signed-off-by: Jon Johnson <jon.johnson@chainguard.dev>
