net/rdesktop: Fix build with OpenSSL 1.1.0
Fix rdesktop build on new OpenSSL in 12.0 and CURRENT. Fix at least one
glaring issue in Jani Hakala's initial patch that went unnoticed for 12
months upstream before being fixed without mention.
Note: Given the general security naivety upstream and lack of new releases
since 2015 despite probably hundreds of errata fixed in git, I don't
recommend anyone actually use this port.
Nevertheless, this change gets it compiling.
