Revert "Enable builds within Github-fork from github.com/blampe/goat"

This reverts commit c7e9854a5aaaff359cff88915df8108c14c4b5f8.

Use global search-replace of "blampe" for "dmullis" instead.

This achieves symmetry between contents of the Github "parent"
repo and the dmullis fork.  Simplifies Github CI tests, and install
for users (via 'go install github.com/...').
