fix(build): fix dev Dockerfile

The dev Dockerfile uses the official Go image as the base for the
final stage, and copies journalctl and dependencies from a debian image.
This is consistent with the production image, but that uses scratch,
while the golang image also uses Debian as base. As a result, if the
debian versions diverge, it's possible to get cryptic errors about
glibc versions, as has recently happened in our CI.

Instead, skip the intermediate step and install systemd in the
final image directly.
