cue: fix import usage detection for partially resolved files

Previously, the usage of imports was deteced by matching
them with unresolved references. This did not work, however,
when passing a previously processed ast.File, with already
resolved references.

The problem was previously undetected, as the CUE builder
would always write out files and parse them back in. Recent
optimizations that elide this step exposed this problem.

This change also makes uses of the newer multi-error
infrastructure and improves some of the naming of vars.
