    rc.d/wg: Match wg ifnames on wg_start
    
      Specifying wg_interfaces="wg0" in /etc/rc.conf causes:
    
        ifconfig: ioctl SIOCSIFNAME (set name): File exists
    
      The interface name matching in the wg script is not matching the
      'wg' interfaces thus trying to set a custom interface name.
    
      Apparently expr does not interpret '+' from regex:
    
        $ expr 'wg0' : 'wg[0-9]+$' && echo matched
        0
    
      Workaround it by using already working expr usage:
        $ expr 'wg0' : 'wg[0-9][0-9]*$' && echo matched
        3
        matched
    
      There is no need to anchor the beginning of line with ^ since
      expr already does that.
