Upgrade to libgit2 v1.3.2

The new version is mostly a security release, with the changes below:
- This provides compatibility with git's changes to address CVE 2022-29187. As a follow up to CVE 2022-24765, now not only is the working directory of a non-bare repository examined for its ownership, but the .git directory and the .git file (if present) are also examined for their ownership.

- A fix for compatibility with git's (new) behavior for CVE 2022-24765 allows users on POSIX systems to access a git repository that is owned by them when they are running in sudo.

- A fix for further compatibility with git's (existing) behavior for CVE 2022-24765 allows users on Windows to access a git repository that is owned by the Administrator when running with escalated privileges (using runas Administrator).

- The bundled zlib is updated to v1.2.12, as prior versions had memory corruption bugs. It is not known that there is a security vulnerability in libgit2 based on these bugs, but we are updating to be cautious.
