Fixes linkage for Ubuntu Wily (15.10).
The issue manifests itself as "undefined symbol: SHA1" error at module loading.

In Ubuntu 14 LTS (Trusty), pkg-config --libs libssl returns -lssl -lcrypto, but in Ubuntu 15.10 (Wily) it returns only -lssl. In the end, websocket.so gets SHA1 symbol (and some more) unresolved.

For unclear reason, this change is not needed for tls.so - it gets linked to libcrypto automatically, despite it is linked only with -lssl flag. Maybe it is something symbol-specific, or something I am completely unaware of.

SSL_BUILDER stuff in Makefile seems to become even more mostruous with the proposed change. Keep in mind that there is ~5 more modules with identical construction in their Makefiles. Rejection of this patch in favor of cleaner solution is appreciated.
