One of the current few steps to run Tailscale on gokrazy is to
specify the --tun=userspace-networking flag:
https://gokrazy.org/userguide/install/tailscale/
Instead, make it the default for now. Later we can change the
default to kernel mode if available and fall back to userspace
mode like Synology, once #391 is done.
Likewise, set default paths for Gokrazy, as its filesystem hierarchy
is not the Linux standard one. Instead, use the conventional paths as
documented at https://gokrazy.org/userguide/install/tailscale/.
Updates #1866
RELNOTE=default to userspace-networking mode on gokrazy
