packagegroup-resin: Install ldd script in balenaOS images

[acostach]

The takeover project currently relies on the ldd script being present in the hostOS pre-migration.

While takeover can be adapted to use this script from a different location, it wouldn't hurt to have ldd in the hostOS from this point on.
