cmd/cue/cmd: fix get go package handling

A referenced alias in a different file in the same package
for a package that was not used within the file in which
the alias was referenced itself, resulted in improper
handling.

Implementation now uses astutil.Sanitize, which allow for
more local import handling, resulting in more robust
generation. This also allows eliminating some package
tracking and the `usedInFile` field.

We could rely more on Sanitize, but that is left up to a
next round.

Fixes #464
