netfilter: xtables: merge xt_MARK into xt_mark
Two arguments for combining the two:
- xt_mark is pretty useless without xt_MARK
- the actual code is so small anyway that the kmod metadata and the module
in its loaded state totally outweighs the combined actual code size.
i586-before:

-rw-r--r-- 1 jengelh users 2592 Feb 10 00:04 xt_MARK.o

text data bss dec hex filename
354 264 0 618 26a xt_MARK.o
223 176 0 399 18f xt_mark.o
And the runtime size is like 14 KB.

+ This option adds the "MARK" target and "mark" match.
+
+ Netfilter mark matching allows you to match packets based on the
+ "nfmark" value in the packet.
+ The target allows you to create rules in the "mangle" table which alter
+ the netfilter mark (nfmark) field associated with the packet.
+
+ Prior to routing, the nfmark can influence the routing method (see
+ "Use netfilter MARK value as routing key") and can also be used by
+ other subsystems to change their behavior.
