Fixes cockroachdb#66404 * Upgrade gazelle to latest version. Go 1.16 updates `go.sum` when gazelle calls `go download`. The new version fixes this issue. See bazel-contrib/bazel-gazelle#1015. * Remove line references in `build/README.md`, because they are not stable. * Set `GOPATH` in various places for bazel based builds and tests in order to work round the case when `go env` fails when `GOPATH` and `HOME` are unset. See golang/go#43938 for the details. * Set `GO111MODULE=off` in `pkg/acceptance/compose/gss/psql/Dockerfile`. Go 1.16 requires `go.mod` in order to build and test the module without `GO111MODULE=off`. Checklist: * [x] Adjust the Pebble tests to run in new version. * [x] Adjust version in Docker image ([source](./builder/Dockerfile)). * [x] Adjust version in the TeamCity agent image ([setup script](./packer/teamcity-agent.sh)) * [x] Rebuild and push the Docker image (following [Basic Process](#basic-process)) * [x] Bump the version in `WORKSPACE` under `go_register_toolchains`. You may need to bump [rules_go](https://github.com/bazelbuild/rules_go/releases). * [x] Bump the version in `builder.sh` accordingly ([source](./builder.sh#L6)). * [x] Bump the version in `go-version-check.sh` ([source](./go-version-check.sh)), unless bumping to a new patch release. * [x] Bump the go version in `go.mod`. You may also need to rerun `make vendor_rebuild` if vendoring has changed. * [x] Bump the default installed version of Go in `bootstrap-debian.sh` ([source](./bootstrap/bootstrap-debian.sh)). * [x] Replace other mentions of the older version of go (grep for `golang:<old_version>` and `go<old_version>`). * [ ] Update the `builder.dockerImage` parameter in the TeamCity [`Cockroach`](https://teamcity.cockroachdb.com/admin/editProject.html?projectId=Cockroach&tab=projectParams) and [`Internal`](https://teamcity.cockroachdb.com/admin/editProject.html?projectId=Internal&tab=projectParams) projects. * [ ] Ask the Developer Infrastructure team to deploy new TeamCity agent images according to [packer/README.md](./packer/README.md) Release note: None
