github: update goveralls tool

The goverall tool had a bug regarding the module versioning of
golang packages see also
https://github.com/mattn/goveralls/pull/222 for more background.
Goveralls is wrapped by another library to make it available for
github actions. So the relevant PR which is referenced here in
LND is:
https://github.com/shogo82148/actions-goveralls/pull/521.
