Subject: [PATCH] build: Enable -mod build flag to be toggled via environment
 variable

This change will enable builds to be performed with the option of
passing the -mod flag to 'go build'. This can be done by optionally
setting the MODMODE environment variable prior to building.

For example, toggling the -mod setting for the build can be
accomplished as follows:

```
$ MODMODE=vendor ./build
```
