ci: allow overriding build target for build-deb

When building packages for buster, I do want to use glibc rather than
musl, because it's being built for a specific distro. Allow a target
argument to be passed through.

(also ci/docker/buster/build-deb.sh was broken because the container
didn't contain the musl target)
