[Buildroot] [PATCH 1/1] package/tailscale: add missing config fixups

[James Hilliard]

There are a number of kernel config fixups required for tailscale to
function properly, these are commonly enabled by default in various
kernel configs but lets make sure they are all enabled here as well.

Committed, thanks.

Out of interest, where did this list of config options come from? I
didn't find anything in the tailscale documentation from a quick look.

Yeah, it's not really documented properly at all, so it was a mix of looking
through the tailscale sources and testing options.
