    evtchn: build fix for Arm
    
    When backporting daa90dfea917 ("pirq_cleanup_check() leaks") I neglected
    to pay attention to it depending on 13a7b0f9f747 ("restrict concept of
    pIRQ to x86"). That one doesn't want backporting imo, so use / adjust
    custom #ifdef-ary to address the immediate issue of pirq_cleanup_check()
    not being available on Arm.
