Subject: [PATCH] fix(post-install): export GZIP in pigz wrapper so level -1
 takes effect

The wrapper assigned GZIP="-1" without exporting it, so pigz never saw
it and compressed at its default level 6. Export it, and refresh
/bin/gzip on re-runs when gzip.original already exists so existing
installs pick up the corrected wrapper.
