Leverage `make build-git` from Gitaly to obtain Git
Git is currently owned by the distribution team, which is great in cases where the Git requires fast updates for example during security upgrades.
Now for other Git upgrades, it means that the Gitaly team has to create about 7 MRs to get the versions upgraded across everything GitLab. Further, the option to ship and apply custom patches is only available in omnibus, which means that Gitaly tests against a different Git than the one we run in production.
Using build-git
we're trying to unify this, but would like this teams input in potential blind spots or other issues.
