Allow --dhcp-option in config file when windows-driver is wintun

When wintun is in use we mutate ip_win32_type to NETSH
and then complain that ip-win32 option should be dynamic or adaptive
if any --dhcp-option directive is present in the config file. This
causes a fatal error.

How to reproduce: specify a --dhcp-option in the config and change the
--windows-driver to wintun.

Fix this behaviour. A typo in the message is also corrected.
