Subject: [PATCH] Fix signature of git_libgit2_opts

On most platforms this doesn't make a difference,
but the PowerPC ABI uses the signature to decide
whether or not to allocate a parameter save area.
Without this, the caller does not, but the callee
assumes it's there causing the callee to overwrite
critical parts of the caller stack.

Fixes #27007
