    wolfssl: add support for OpenVPN
    
    Support for wolfSSL has been upstreamed to the master OpenVPN branch
    in f6dca235ae560597a0763f0c98fcc9130b80ccf4, so we can use wolfSSL
    directly in OpenVPN. So no more needed differnt SSL engine for OpenVPN
    in systems based on wolfSSL library
    Compiled && tested on ramips/mt7620, ramips/mt7621
