sctp: move SCTP_PAD4 and SCTP_TRUNC4 to linux/sctp.h

Browse Source 
Move these two macros from net/sctp/sctp.h to linux/sctp.h, so that
it will be enough to include only linux/sctp.h in nft_exthdr.c and
xt_sctp.c. It should not include "net/sctp/sctp.h" if a module does
not have a dependence on SCTP module.
