netfilter: nat: remove nf_nat_l3proto.h and nf_nat_core.h
The l3proto name is gone, its header file is the last trace.
While at it, also remove nf_nat_core.h, its very small and all users
include nf_nat.h too.
before:
text data bss dec hex filename
22948 1612 4136 28696 7018 nf_nat.ko
after removal of l3proto register/unregister functions:
text data bss dec hex filename
22196 1516 4136 27848 6cc8 nf_nat.ko
checkpatch complains about overly long lines, but line breaks
do not make things more readable and the line length gets smaller
here, not larger.
