ndisc6: allow the package can be empty

FILES_${PN} is set to null in original .bb file, this would cause
ndisc6 main package is missing, then one build error will happen:

ERROR: ndisc6 not found in the base feeds (qemux86 i586 x86 noarch any all).

To fix this, need to set ALLOW_EMPTY_${PN} = "1".
