systemd/generate: change type to notify

Change the type of units generated with --new from "forking" to
"notify".  This brings Podman closer to systemd and opens up
Podman to a number of use cases (see #5572).

Units generated without --new remain with `type=forking`.  I
experimented a bit with adding a `--sdnotify` flag to `podman start` but
it doesn't really work well since we're competing with the default
sdnotify mode set during container creation.

Fixes: #5572
