    wolfssl: add config flag for Curve448
    
    This enables building WolfSSL with Curve448, which can be used by
    Strongswan. This has been tested on a Linksys E8450, running OpenWrt
    22.03-rc4.
    
    This allows parity with OpenSSL, which already supports Curve448 in
    OpenWrt 21.02.
    
    Fixes openwrt/packages#18812.
