AprRequirement should not short-circuit if apr is installed

If apr is installed, we still want to grab it during dependency
resolution in case we need to pass options to the generated dependency.

In other words, it doesn't make sense for the satisfiable condition to
include the default formula, as the default formula is the fallback for
when the requirement is *not* satisfied.
