[NETFILTER]: x_tables: replace IPv4 dscp match by address family independent version
This replaces IPv4 dscp match by address family independent version.
This also
- utilizes dsfield.h to get the DS field in IPv4/IPv6 header, and
- checks for the DSCP value from user space.
- fixes Kconfig help text.
