dependencies: Obey the user setting asdf.opt_out
In the gdk.yml users are able to opt-out from using asdf. This used be taken into account in support/exec-cd, but recently code was changed 1 to use GDK::Dependencies instead. This change didn't take asdf.opt_out into account.
Teach GDK::Dependencies to check for asdf.opt_out? before checking if asdf is even available.
