- apt-get is slow, takes up ~1m40s just to install deps, fix it by not
using it. instead use alpine linux for codeberg ci, which brings build
time down to 25s.
- And since alpine uses musl, it's probably a good idea to use it on our
ci since it might catch us using any glibc extensions. The github ci
can keep using ubuntu.
- remove duplication of CFLAGS by having it on a separate file instead.
- remove pull_request from github ci since we no longer accept PRs
there.
