[XFRM]: Add module alias for transformation type.

Browse Source 
It is clean-up for XFRM type modules and adds aliases with its
protocol:
 ESP, AH, IPCOMP, IPIP and IPv6 for IPsec
 ROUTING and DSTOPTS for MIPv6

It is almost the same thing as XFRM mode alias, but it is added
new defines XFRM_PROTO_XXX for preprocessing since some protocols
are defined as enum.
