[roll] Roll fuchsia [kernel][x86] Remove address constants from start-up

This change removes the remaining address constants in the initialized
data of the x86 kernel:
* In start.S, address-immediates are replaced by %rip-relative
  references;
* An unnecessary identity-mapped GDT reload that assumed a constant
  difference between the kernel's physical and virtual load addresses
  was removed;
* The _temp_gdt address used in the definition of our _temp_gdtr was
  defined as relro
