[PATCH net] selftests: drv-net: add configs for the TSO test

[Jakub Kicinski]

Add missing config options for the tso.py test, specifically
to make sure the kernel is built with vxlan and gre tunnels.

I noticed this while adding a TSO-capable device QEMU to the CI.
Previously we only run virtio tests and it doesn't report LSO
stats on the QEMU we have.

I think the above it's not strictly needed, because it's selected by gre
and vxlan (indirectly), but it should not hurt, nor I think we have
minimal non redundant knobs list in other config files.

Oops, you're right. I'll respin after 

  netlink: specs: rt-link: decode ip6gre

gets thru CI, this change alone fixed TSO but broke the stats test :S
