[patch][master][langdale] libgit2: upgrade to 1.5.1

[chee.yang.lee]

From: Chee Yang Lee <chee.yang.lee@intel.com>

This is a security release to address CVE-2023-22742: when compiled
using the optional, included libssh2 backend, libgit2 fails to verify
SSH keys by default.

When using an SSH remote with the optional, included libssh2 backend,
libgit2 does not perform certificate checking by default. Prior versions
of libgit2 require the caller to set the `certificate_check` field of
libgit2's `git_remote_callbacks` structure - if a certificate check
callback is not set, libgit2 does not perform any certificate checking.
This means that by default - without configuring a certificate check
callback, clients will not perform validation on the server SSH keys and
may be subject to a man-in-the-middle attack.

A patch doing this same upgrade has been sent yesterday by Alex Kanavin
and is already in master.
