Subject: [PATCH] `libgit2-sys`: use `src` instead `.git` as vendored indicator

When someone vendored `libgit2-sys` he may exclude `.git` folder.

When such things happened an attempt to build it may lead to error like: `fatal: not a git repository (or any of the parent directories): .git`.

The only way to fix it is using system's `libgit2` which may lead to `invalid version 0 on git_proxy_options; class=Invalid (3)` at some cases.
