ci/eval: allow configuration of the system to eval attrpaths on

Right now, there are some paths that don't even get exposed to certain
systems (notably Darwin, but some outliers exist for Linux such as the
Darwin-specific Hackage overlay) for one reason or another, usually
because of assertions like `stdenv.isLinux`. To catch these scenarios,
this change implements a way to specify the system to evaluate attrpaths
on, and makes it default to the system that we're evaluating outpaths
for.
