rm_work: Handle race with -inital tasks

There is a race with rm_work when tasks run deltask do_build since
do_rm_work becomes a floating task. Handle this by injecting
the populate_sysroot/lic dependencies manually if the tasks returned
are empty. This depends on a change to fix bb.build.preceedtask() in
bitbake too.
