Use unsigned constants for ICMP6 filters [BZ #22489]
The core problem here is that the filter array elements are unsigned
but the computed constants are signed. This both causes a
signededness conversion at the &= step and may cause undefined
behavior if the MSB is being modified. This patch uses unsigned
constants to avoid both cases. - DJ
