clientupdate: cache CanAutoUpdate, avoid log spam when false

Browse Source 
I noticed logs on one of my machines where it can't auto-update with
scary log spam about "failed to apply tailnet-wide default for
auto-updates".

This avoids trying to do the EditPrefs if we know it's just going to
fail anyway.

Updates #282
