v4l-utils: add libudev-zero dependency

When libudev-zero is enabled, v4l-utils links against it, and the
package build fails due to a missing dependency:

Package v4l-utils is missing dependencies for the following libraries:
libudev.so.1

As disabling udev doesn't seem to be supported in v4l-utils, simply add
the dependency to fix the build.
