nodejs: Revert "nodejs: disable ssl2 and ssl3 when openssl is not built"

This reverts commit e712638b.

The config options --without-ssl2 and --without-ssl3 are intended to be used if
nodejs is built with the bundled OpenSSL library for excluding the SSL2 and
SSL3 features.

Both options are actual only evaluated if --without-ssl is not set:

$ cat configure | grep configure_openssl -n -A 13
619:def configure_openssl(o):
620-  o['variables']['node_use_openssl'] = b(not options.without_ssl)
621-  o['variables']['node_shared_openssl'] = b(options.shared_openssl)
622-  o['variables']['openssl_no_asm'] = (
623-    1 if options.openssl_no_asm else 0)
624-
625-  if options.without_ssl:
626-    return
627-
628-  if options.ssl2:
629-    o['defines'] += ['OPENSSL_NO_SSL2=1']
630-
631-  if options.ssl3:
632-    o['defines'] += ['OPENSSL_NO_SSL3=1']
