Disble gosec from checking errors

Occasionally, the code quality report will include gosec "error not
checked" type linting errors instead of the ones from errcheck.
This produces unnecessary noise in the merge request UI.

errcheck seems to capture a wider range of issues, and, for this
family of issues, can be configured more granularly.
