    xen-access: Correct default value of write-to-CR4 switch
    
    The current implementation configures the test environment to always
    trap on writes to the CR4 control register, even on ARM. This leads to
    issues as calling xc_monitor_write_ctrlreg on ARM with VM_EVENT_X86_CR4
    will always fail.
