initscripts: don't bg mk_dirs in populate-volatile

If a directory needs to be created to create something else in volatiles,
there's no guarantees on ordering due to the backgrounding. We can't guarantee
with certainty that the create directory commands are complete before the
later ones run. This ensures that we wait for directory creations to complete
before we proceed.

Chris Hallinan hit an actual failure due to this back in March of last year.
