ParagonIE_Sodium_Compat::use_fallback() protected WP 1.0

Should we use the libsodium core function instead? This is always a good idea, if it's available. (Unless we're in the middle of running our unit test suite.)

If ext/libsodium is available, use it. Return TRUE. Otherwise, we have to use the code provided herein. Return FALSE.
