bitbake: runqueue: dry-run real tasks when BB_SETSCENE_ENFORCE is set

Browse Source 
For the purposes BB_SETSCENE_ENFORCE is designed for (in OE, it is used
by the installation process for the extensible SDK), we don't actually
need the whitelisted real tasks to execute - we just need to have them
in the dependency tree so that we get all of the setscene tasks they
depend on to run. Therefore we can actually dry-run those real tasks
i.e. they won't be run (and thus we won't waste a significant amount of
time doing so) and won't be stamped as having run either. We do already
have a dry-run mode in BitBake (activated by the -n or --dry-run command
line option), but it dry-runs the setscene tasks as well which we don't
want here.

Note that this has no effect on the checking we are doing with
BB_SETSCENE_ENFORCE to ensure that only whitelisted real tasks are
scheduled to run - that's handled separately.

Fixes [YOCTO #10369].
