libostree: add patch to fix compilation error

Fix the following compilation error:
src/libostree/ostree-repo-pull.c:1493:1: error: no previous prototype
for '_ostree_repo_verify_bindings' [-Werror=missing-prototypes]

The patch is submitted upstreams (8d3d14503b3105f93db635022e881e02688f2db4)
and should be removed in the next version bump.
