Preserve --dhcp-option values from local config
Commit
2dfc4f8 ("dns: deal with --dhcp-options when --dns is active")
has changed the way how --dhcp-option values are stored. Instead of
storing them directly in tuntap_options, they are now stored in
dns_options->from_dhcp.
Before connect, we save options before --pull is applied, and for that
we call clone_dns_options(). However, this was missing to clone the
"from_dhcp" struct, and as a result, the values of --dhcp-option from
the local config have been lost.
Fix by adding shallow-copying of dhcp_options to clone_dns_options(). It
is safe to do because it only contains fixed-size arrays, scalar types
and pointers to the strings which this struct doesn't own.
