systemd.bbclass: support user units in postinst and prerm hooks

Handle user units in a manner similar to system units where possible.
Not everything is supported by systemd, but systemd limitations only
affect runtime package management - during update user services are not
reloaded/restart and each user must re-login or manually restart
services.
