Fix dependency issues with rpm package

[jsoriano]

github.com/cavaliercoder/go-rpm has been renamed, and it seems to be causing some issues between the main go.mod and the go.mod of the custom beats generator.

Update dependencies to the new location.

Also, force the use of the current commit when testing the generator, to avoid using mixed versions (see comment).

Generator tests are failing in master with:
