x86-64/EFI: don't call EfiResetSystem() from machine_halt()

c/s 23615:d19e77844267 was a little too eager in adding calls to EFI
runtime services: machine_halt() doesn't really want to power off the
machine, but that's what EfiResetSystem(EfiResetShutdown, ...) (called
through efi_halt_system()) does.
