Kernel: Load executables on demand when symbolicating

Browse source 
Previously we would map the entire executable of a program in its own
address space (but make it unavailable to userspace code.)

This patch removes that and changes the symbolication code to remap
the executable on demand (and into the kernel's own address space
instead of the process address space.)

This opens up a couple of further simplifications that will follow.
