ARM: s3c2410_defconfig: Fix invalid values for NF_CT_PROTO_*

NF_CT_PROTO_DCCP/SCTP/UDPLITE were switched from tristate to boolean so
defconfig needs to be adjusted to silence warnings:
	warning: symbol value 'm' invalid for NF_CT_PROTO_DCCP
	warning: symbol value 'm' invalid for NF_CT_PROTO_SCTP
	warning: symbol value 'm' invalid for NF_CT_PROTO_UDPLITE
