Change kernel link type

Browse Source 
Kernel is now compiled and linked into a raw binary instead of intel
hex. This raw binary can be loaded into the correct address by the
bootloader.

I wanted this to be an o65 file, but ld65 kept complaining about it.
Honestly though having this be a straight binary makes it easier to
load, but we can't relocate it.
