This has already been fixed back in 2019: https://git.savannah.nongnu.org/cgit/lwip.git/commit/?id=90b2a6b4c4875379d18014673bafaddc1079d1af

However, let's just make sending the hostname in discover a default, I guess it's better that way.

The hostname option is not included in the DHCP discover message.

Presently it is only explicitly included in 'dhcp_select', 'dhcp_renew' and 'dhcp_rebind' messages and only after 'dhcp_discover_request_options' are added.

The same `#if LWIP_NETIF_HOSTNAME` block adding hostname to the messages should be included in `dhcp_discover`
