libgit2: Fix CVE-2024-24575 and CVE-2024-24577

CVE-2024-24575:
libgit2 is a portable C implementation of the Git core methods provided
as a linkable library with a solid API, allowing to build Git functionality
into your application. Using well-crafted inputs to `git_revparse_single`
can cause the function to enter an infinite loop, potentially causing a
Denial of Service attack in the calling application. The revparse function
in `src/libgit2/revparse.c` uses a loop to parse the user-provided spec
string. There is an edge-case during parsing that allows a bad actor to
force the loop conditions to access arbitrary memory. Potentially, this
could also leak memory if the extracted rev spec is reflected back to the
attacker. As such, libgit2 versions before 1.4.0 are not affected. Users
should upgrade to version 1.6.5 or 1.7.2.

CVE-2024-24577:
libgit2 is a portable C implementation of the Git core methods provided
as a linkable library with a solid API, allowing to build Git functionality
into your application. Using well-crafted inputs to `git_index_add` can
cause heap corruption that could be leveraged for arbitrary code execution.
There is an issue in the `has_dir_name` function in `src/libgit2/index.c`,
which frees an entry that should not be freed. The freed entry is later
used and overwritten with potentially bad actor-controlled data leading to
controlled heap corruption. Depending on the application that uses libgit2,
this could lead to arbitrary code execution. This issue has been patched
in version 1.6.5 and 1.7.2.
