[yocto] Install files in sysroot but not rootfs (ala -dev)

[Koehler, Yannick]

I have some file to install in the sysroot/${MACHINE}/usr/share/cmake/Modules, but when I do so, those files also end up on the target.

Is moving those files from FILES_${PN} to FILES_${PN}-dev the proper way to fix that and what is the logic that make it so that -dev packages are installed in the sysroot but not in the rootfs?
