package/socat: disable openssl for static build

socat's configure script does not take the zlib dependency into
account when linking with libssl, and therefore fails at detecting
libssl in BR2_STATIC_LIBS=y configurations.

Since there is no easy way to add the zlib dependency, just disable
openssl support for static builds.

This is not fixing a build failure: libssl was not detected in
BR2_STATIC_LIBS=y configurations, so what this commit does is make it
explicit.
