Draft: build: init: set compress=1
Configure abuild to use the fastest possible compression.
Depends on https://gitlab.alpinelinux.org/alpine/abuild/-/merge_requests/340
Thoughts:
- Does BPO use this config? Maybe we should have a way to set it back to -9 for BPO?
- This doesn't solve the "running gzip through QEMU" issue still...
