Panic on "Build constraints exclude all Go files"

[dustin-ward]

When wharf encounters a package that contains no "buildable" Go files a panic occurs:

github.com/elastic/beats/filebeat as an example:

unable to load packages: unable to load github.com/elastic/beats/v7/libbeat/processors/add_docker_metadata: build constraints exclude all Go files in /u/kishku1/projects/wharf-work/beats/libbeat/processors/add_docker_metadata

i.e. All files within this package are tagged in a way that zOS is excluded. The best solution for most cases is to simply apply the zos tag to each file within the package.
