Fix broken DHCP options
Commit
2dfc4f ("dns: deal with --dhcp-options when --dns is active")
broke support for --dhcp-options. It removed the setting of the
DHCP_OPTIONS_DHCP_OPTIONAL flag for some DHCP options. This flag is
required for those options to be applied correctly, as it is used
when building the DHCP options string that is passed to the TAP driver.
This commit fixes the issue by restoring the setting of this flag.
