Fix undefined symbol errors on readw/writew: arch/io.h, not sys/io.h.

The undefined symbols naturally weren't relocated by kexec's linker, so
each compiled `call` instruction branched into the middle of itself. The
CPU proceeded to interpret the un-relocated address as instructions,
resulting in an undefined opcode fault. Since at this point no IDT is
loaded, that turned into a triple-fault and reboot.

The bug was only visible when running kexec with --console-vga.
