[gnome-continuous-yocto/gnomeostree-3.28-rocko: 4126/8267] classes/package*: Add support for PACKAGE_WRITE_DEPS

[Emmanuele Bassi <ebassi src gnome org>]

commit bc7162a46cebfec3896f95081bc2f635efa509f2

    classes/package*: Add support for PACKAGE_WRITE_DEPS
    
    Add a new variable to allow markup of postinstall (and preinst)
    script dependnecies on native/cross tools.
    
    If your postinstall can execute at rootfs creation time rather than on
    target but depends on a native tool in order to execute, you need to
    list that tool in PACKAGE_WRITE_DEPENDS.
