The issue was that our build pipeline uses 'go get' call to install
golint, which changed the go.mod/go.sum files (not good, but I hadn't
noticed before). Due to Golang bug #44129, this caused breakage on the
dependencies of certain modules we use.
The fix was to switch to 'go install golang.org/x/lint/golint@latest'.
The addition of '@latest' puts 'go install' in module aware mode, which
no longer changes go.mod file in the current directory. This is better,
and it also avoids bug #44129.
This commit also has a change due to `go mod tidy`. Finally, I had to
add a longer timeout for the golangci-lint installation step in the
github actions workflow, since that seems to take a bit over a minute
now. This step is usually cached on subsequent runs, so we hadn't seen
that failure before.
