Brad Fitzpatrick 0a1eb8c4da ipn/ipnlocal: don't answer single-label names from quad-100 ...

Since 7e609b258 (v1.102), quad-100 looks up MagicDNS names in
nodeBackend.nodeByName, which also holds short-name keys for in-process
dials. So a query for "foo." matched peer "foo.tail-scale.ts.net" and
was answered with its Tailscale IP. 1ec348784 fixed that for MagicDNS
off; this fixes it for MagicDNS on, too, matching pre-1.102 behavior.
The OS applies the search domain to short names before they reach
quad-100, so a single-label query is a root zone name, not a tailnet
name, and must be forwarded (e.g. to LAN mDNS/LLMNR or a global
nameserver). Short names still work for in-process dials via
NodeByName.
