Fix --dns options for TAP adapter

Commit

    2dfc4f ("dns: deal with --dhcp-options when --dns is active")

has accidentally removed setting of the DHCP_OPTIONS_DHCP_OPTIONAL
flag when copying --dns options. This flag is required to apply options
via DHCP string, which we do for TAP adapter. As a result, --dns options
stopped working for TAP.

Fix by setting this flag when copying --dns options to tuntap_options.
