Makefile: apply Git ref advertisement buffering patches
Prior to these patches, Git used unbuffered writes for upload-pack ref
advertisements, with one or two write syscalls per ref. In
repositories with many refs that adds up to a lot of syscalls. These
patches add stdio buffering for the ref advertisement writes.
Also see gitlab-com/gl-infra/scalability#1257.
