Add go-vendor-tools to sandcastle image

[gotmax23]

go-vendor-tools is a new tool maintained by the Fedora Go SIG which helps with generating vendor archives and helping vendored Go packages follow the Licensing Guidelines. It is currently only available in Fedora, so we install it with pip.

Relates: packit/packit#2382

This is a draft until https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2024-6545265745 goes through.

The tests are currently broken (fixing them is tracked in packit/deployment#543), but the image builds successfully, so let's merge this.
