PPP: restore PPPoE devices without Ethernet ARP support, i.e. PPPoE only devices

Ethernet support is required for PPPoE but Ethernet support is only set
by default in opt.h if ARP is enabled, which is wrong because the right
condition is ARP and/or PPPoE, unfortunately PPPOE_SUPPORT can't be used
in opt.h because it is not defined if ppp_opts.h is not included before
opt.h in user code.

Fixup the LWIP_ETHERNET configuration value in ppp_opts.h in order to
force Ethernet support if PPPoE is enabled.

Fixes: 3ad2ad2329 ("Remove reference to PPPOE_SUPPORT in opt.h - leads
    to compile errors because it has no default definition (only in
    ppp_opts.h)"
