connman: remove xtables build fix patch

This was added in 0dece985 to deal with kernel headers 4.5 -> 4.5.4
breakage. Unfortunately the fix in 4.5.5 and 4.6+ doesn't deal correctly
with this causing more build breakage, so we'd rather "break" for the
small range of 4.5.x versions broken than for the rest of time.
