cmd/gomote: ignore some new paths for deleting in gomote push

Since Go 1.9, the cmd/go tool has rearranged and the Go build now
writes some auto-generated files in different places. Don't delete
these auto-generated files in a "gomote push".

Otherwise you can't iteratively:

* hack locally
* gomote push
* test remotely

... without getting remote errors about missing files.
