Fix dirty_*if_SUITE after file rewrite
Code loading is done through dirty IO now, causing the
dirty_scheduler_exit tests to fail as they block their own progress
by invoking erts_debug:dirty_io(wait, _); the spawned processes
will exit normally before we have a chance to kill them.
To get around this, we perform a dry run to ensure that all required
code is loaded. It isn't particularly pretty (or fast) but it saves
us the hassle of maintaining a module list (cf. embedded mode).
