Rebuild Intel IPU7 camera against updated jsoncpp

[ryanrhughes]

The installed Intel IPU7 camera HAL requires libjsoncpp.so.26, but jsoncpp 1.9.8-1 now provides libjsoncpp.so.27. The HAL consequently fails to load, leaving applications with no usable camera stream.

Bump intel-ipu7-camera from 1.0.5-1 to 1.0.5-2 so the release builder recompiles the HAL against the current library. Add jsoncpp to rebuild_on and use bin/sync-rebuilds intel-ipu7-camera to record the x86_64 dependency version, so future jsoncpp updates also trigger a package release.

Validation: bin/sync-rebuilds --self-test, a second targeted sync with no further changes, package metadata validation, bash -n, makepkg --printsrcinfo, and git diff --check all passed. A full package build and camera hardware test remain for the rebuilt package.
