Fix file ownership issues during install [2/2]

The rake tasks run during install need write access to db/ and Gemfile.lock (for
the crowbar user).

Additionally this removes some "require chef" lines from the crowbar barclamp
which should no longer be needed as those were moved to the chef barclamp a
while ago.
