kvm tools: ioport: add arch callback to remap IRQ lines for ioport devices

If an architecture other than x86 wants to make use of ioport devices, the
interrupt lines will likely need remapping from their fixed values.

This patch allows an architecture callback, ioport__map_irq, to map
interrupts as appropriate.
