headers/kernel: Include declarations of initialization functions in image.h.

No "real" functional change, but this causes GCC7 to throw errors when
these functions are declared without the image_id argument, which
in some files they were (as this commit repairs.)

This change is largely inconsequential on x86, but on callee-cleanup-args
targets, leaving out the argument would probably cause stack corruption.
