main: get rid of ACTION_DONE (#3849)

the ACTION_DONE was introduced in the 4288f61921 (dbus: automatically
generate and install introspection files ) commit and was used in
systemd --introspect command.

Later 'introspect' command was removed in the ca2871d9b (bus: remove
static introspection file export) commit and have no users anymore.

So we can remove it.
