[pkg-go] [PATCH] dakweb: add /golang/import_paths query

[Michael Stapelberg]

Please keep me CC'ed, I’m not subscribed to debian-dak.

Please consider merging the following patch which you can find
attached to this email or at
https://github.com/stapelberg/dak/tree/golang. Thank you!

This query will replace a heuristic in dh-make-golang(1) and help us resolve
Go build dependencies into Debian build dependencies accurately.
