ipxedust: add nap.h to arm64 build to set NAP_NULL to support u-boot

- see ipxe/ipxe#605 (reply in thread) - "This will cause iPXE to leave the CPU spinning instead of putting it to sleep, and will avoid the problems on U-Boot." - Seems harmless on non U-Boot machines -- the CPU will spin during the key timeout (2s?) but that's about it.
