Follow-up to #3166 which did the cmake part of this. This type/define is
not used.

-dnl CURL_CONFIGURE_CURL_SOCKLEN_T
-dnl -------------------------------------------------
-dnl The need for the curl_socklen_t definition arises mainly to properly
-dnl interface HP-UX systems which on one hand have a typedef'ed socklen_t
-dnl data type which is 32 or 64-Bit wide depending on the data model being
-dnl used, and that on the other hand is only actually used when interfacing
-dnl the X/Open sockets provided in the xnet library.
