net/IPv[46]Address: add cast to void* to fix GCC9 build failure
    
    Fixes:
    
     src/net/IPv4Address.hxx: In member function 'constexpr IPv4Address::operator SocketAddress() const':
     src/net/IPv4Address.hxx:171:24: error: a reinterpret_cast is not a constant expression
       171 |   return SocketAddress((const struct sockaddr *)&address,
           |                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
     src/net/IPv6Address.hxx: In member function 'constexpr IPv6Address::operator SocketAddress() const':
     src/net/IPv6Address.hxx:138:24: error: a reinterpret_cast is not a constant expression
       138 |   return SocketAddress((const struct sockaddr *)&address,
           |                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
