classes: drop image dependencies on TOPDIR variable

We don't need a dependency on this variable changing, and having one
causes locked signature warnings during eSDK installation if you have
INITRAMFS_IMAGE_* set (since TOPDIR will always be different between
the eSDK and the environment in which it was built).

Relates to [YOCTO #12102].
