Robert Griesemer 1f446432dd cmd/compile: fix error msg mentioning different packages with same name ...

This is a regression from 1.6. The respective code in importimport
(export.go) was not exactly replicated with the new importer. Also
copied over the missing cyclic import check.

Added test cases.

Fixes #16133.
