device-sony-nicki: avoid overriding udev v4l rule in /etc (MR 4768)

Postmarketos-base-downstream-disable-udev-v4l symlinks
/lib/udev/rules.d/60-persistent-v4l.rules to /dev/null, so depend on
this package instead.  The dependency is added to downstream kernel
subpackage, as issue *should* only affect downstream kernel.
