x86/kexec: Add relocate_kernel() debugging support: Load a GDT
There are some failure modes which lead to triple-faults in the
relocate_kernel() function, which is fairly much undebuggable
for normal mortals.
Adding a GDT in the relocate_kernel() environment is step 1 towards
being able to catch faults and do something more useful.
