Patch app-services' vendored uniffi_bindgen

In tor-browser#40420 (closed) we went down the rabbit hole again investigating non-reproducible Android builds. Part of the problem (as described in tor-browser#40420 (comment 2733897)) is that I never upstreamed our fix from #40208 (closed) and we hit the same issue but in a newer version.

I'm finally upstreaming the patch, but in the meantime we need to hot patch the vendored version used in the application-services build process. The hack is ugly, but I think we need to accept this until we get the fix in an upstream version.
