oom: Add support for user unit ManagedOOM property updates Compared to PID1 where systemd-oomd has to be the client to PID1 because PID1 is a more privileged process than systemd-oomd, systemd-oomd is the more privileged process compared to a user manager so we have user managers be the client whereas systemd-oomd is now the server. The same varlink protocol is used between user managers and systemd-oomd to deliver ManagedOOM property updates. systemd-oomd now sets up a varlink server that user managers connect to to send ManagedOOM property updates. We also add extra validation to make sure that non-root senders don't send updates for cgroups they don't own. The integration test was extended to repeat the chill/bloat test using a user manager instead of PID1.

Drop split-usr and unmerged-usr support As previously announced, execute order 66: https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html The meson options split-usr, rootlibdir and rootprefix become no-ops that print a warning if they are set to anything other than the default values. We can remove them in a future release.

meson: use jinja2 for unit templates We don't need two (and half) templating systems anymore, yay! I'm keeping the changes minimal, to make the diff manageable. Some enhancements due to a better templating system might be possible in the future. For handling of '## ' — see the next commit.
