commit 1951ff168a introduced a check so
that conmon is not moved to a new cgroup when podman is running inside
of a systemd service. This is helpful to integrate podman in systemd
so that the spawned conmon lives in the same cgroup as the service
that created it.
Unfortunately this breaks when podman daemon is running in a systemd
service since the same check is in place thus all the conmon processes
end up in the same cgroup as the podman daemon. When the podman
daemon systemd service stops the conmon processes are also terminated
as well as the containers they monitor.
Improve the check to exclude podman running as a daemon.

First and foremost: use ephemeral (/run, $XDG) directories
for systemd unit files, so as not to vandalize a working system.
Second, refactor common systemd-related functionality into
a new helper file, loaded by the systemd-related tests.
Shared functionality includes:
* setting $XDG_RUNTIME_DIR if unset and rootless
* setting $UNIT_DIR for use by tests
* new systemctl() and journalctl() functions, which
include "--user" when rootless (why can't systemd
figure this out on its own?)
