The correct entry for this lib is 'openssl/nolink', not
'openssl_headers'.
In configurejson2cmake's helper.py we already have
this information encoded such that the no_link_so_name field of
'openssl' points to 'openssl_headers'. Extend configurejson2cmake to
take this into account, and re-generate src/network/configure.cmake.
Pick-to: 6.0
