    kexec: some #include adjustments
    
    In the context of working on x86's elf_core_save_regs() I noticed there
    were far more source files getting rebuilt than I would have expected.
    While the main offender looks to have been fixmap.h including kexec.h,
    also drop use of elfcore.h from kexec.h.
    
    While adjusting machine_kexec.c also replace use of guest_access.h by
    domain_page.h.
