x86/kexec: Add data section to relocate_kernel

Now that it's handled sanely by a linker script we can have actual data,
and just use %rip-relative addressing to access it.

If we could call the *copy* instead of the original relocate_kernel in
the kernel text, then we could use %rip-relative addressing everywhere.
