quirc: Use dylib with absolute install name on Darwin

[toonn]

Description of changes

This is a prerequisite for fixing ffmpeg_7-full on Darwin. It's a common pattern in Nixpkgs to use an absolute install name.

I upstreamed the dylib renaming in dlbeer/quirc#144 but the patch needs to be vendored because upstream changes mean it doesn't apply to the packaged release.
The patch is not strictly necessary but means the next version bump will be easier as dropping the patch will be sufficient, rather than remembering to make the other extension related changes.

I'm changing this to draft. After talking to @emilazy, I think it's better to fetchpatch the patches, or bump to unstable and update the vendored patch, that way that doesn't have to be done next version bump and I can fix whatever causes patch unexpectedly ends in middle of line.

Looks fine to me now, should this be merged in the current state?

@7c6f434c, yep, this is ready IMO.
