seccomp: add timerfd_create and timerfd_settime to the whitelist
libusb calls timerfd_create() and timerfd_settime() when it's built with
timerfd support.
Command to reproduce:
-device usb-host,hostbus=1,hostaddr=3,id=hostdev0

Reading a few hundred MB from a USB drive on x86_64 shows this syscall distribution.
Therefore the timerfd_settime priority is set to 242.
