CA-392459: Avoid opening /dev/mem when calling biosdevname

biosdevname opens /dev/mem to read the $PIR PCI interrupt routing table. This fails with Secure Boot enabled and causes a warning in the kernel. log. Since the $PIR PCI interrupt routing table is used for routing PCI interrupts to ISA IRQs, it is not useful on any modern system so pass "-x" to biosdevname to avoid this behaviour.
