libxt_tcp: always print the mask parts

0xFF is unlikely to happen (given that ALL translates to 0x3F at
most), but assuming that through magic, 0xFF was put into memory,
iptables -S/iptables-save would ignore printing it, practically
outputting just one argument to --tcp-flags which currently wants two.
