util/userfaultfd: Support /dev/userfaultfd
Teach QEMU to use /dev/userfaultfd when it existed and fallback to the system call if either it's not there or doesn't have enough permission.
Firstly, as long as the app has permission to access /dev/userfaultfd, it always have the ability to trap kernel faults which QEMU mostly wants. Meanwhile, in some context (e.g. containers) the userfaultfd syscall can be forbidden, so it can be the major way to use postcopy in a restricted environment with strict seccomp setup.
