databases/mongodb-tools: Drop Go version check

[des]

Summary

This port had code to verify that it was being built with the exact Go
version listed in its go.mod. This is based on a misunderstanding,
since the version listed in go.mod describes the feature set, not the
implementation, and Go implementations are backward compatible. Since
the oldest supported Go version is newer than what the port requires,
we can simply drop the check.

Thanks for looking into this, but our activity is crossing the beams. I have a commit ready for a while, but the git server is not giving me the latest revisions on pull so it blocks my push.

The mirrors are working again, you should be able to pull now.
