go: include vendored modules
RHEL requires the source code for dependencies to be included in the srpm. The spec file already expects that, but we've only included the vendored modules (i.e., the `vendor` directory) in the `rhel-8.2.` branch. Move vendoring to master, so that we can build RHEL packages from it as well. This commit is the result of running `go mod vendor`, which includes the vendored sources and updates go.mod and go.sum files. Fedora requires the opposite: dependencies should not be vendored. The spec file already ignores the `vendor` directory by default.
