revert(3p/git): Revert merge of git upstream at v2.26.2

This causes cgit to serve error pages, which is undesirable.

This reverts commit 5229c9b232, reversing
changes made to f2b211131f.

-# A few subtle things about the request in this test:
-#
-#  - the server must have commit-graphs present and enabled
-#
-#  - the history is such that our want/have share a common ancestor ("base"

-#
-#  - we send only a single have, which is fewer than a normal client would
-#    send. This ensures that we don't parse "base" up front with
-#    parse_object(), but rather traverse to it as a parent while deciding if we
-#    can stop the "have" negotiation, and call parse_commit(). The former
-#    sees the actual object data and so always loads the three oid, whereas the
-#    latter will try to load it lazily.

-#  - we must use protocol v2, because it handles the "have" negotiation before
-#    processing the shallow directives
