Draft: systemd/systemd: rework bootstrap logic and enable more features

Notable additions: systemd-journald-upload which depends on libcurl.

Before undrafting:

• move curl-util patch to a pmos/systemd release (there is currently no error handling)
• check makedepends for less bootstrap dependencies
• confirm unintended suspicion: nice (unintended) benefit: bpo no longer breaks
• update commit-msg

Part of: systemd#1
