[iptables PATCH 05/11] iptables/Makefile: Reorg variable assignments

[Phil Sutter <phil@nwl.cc>]

Introduce helper variables holding SOURCES, LDADD and CFLAGS used by
both legacy and nft builds. Specify also internal header files, builds
should depend on them. Doing that, reorder lists for clarity.
