plumbing: http, Fix empty repos on Git v2.41+
Git v2.41.0 comes with [changes](https://github.com/git/git/commit/933e3a4ee205353d8f093d5dfcd226fa432c4e58)
that breaks go-git's assumptions for when detecting empty repositories.
Go-git expects a flush instead of the first hash line. Instead, a dummy capabilities^{}
with zero-id is returned. The change aims to allow for identifying
the object format even when cloning empty
repositories.
