Initially, libudev detection was bundled with --enable-mpath because qemu-pr-helper was the only user of libudev. Recently however the USB U2F emulation has also started using libudev, so add a separate option. This also allows 1) disabling libudev if desired for static builds and 2) for non-static builds, requiring libudev even if multipath support is undesirable. The multipath test is adjusted, because it is now possible to enter it with configurations that should fail, such as --static --enable-mpath --disable-libudev.
