Add "runtime_library_dirs = ssl_libs" to the _socket Extension

specification so that the proper runtime ld.so path gets compiled into
the extension.  This fixes _socket for Solaris systems with libssl and
libcrypto in non-standard locations and should be fine for other
systems as well.  Closes SF bug #565710.

Forward port candidate for Python 2.3 (I'll work on that).
