config: defer creating the base lnd dir until all flag parsing is done

Browse Source 
In this commit, we defer creating the base lnd directory until all flag
parsing is done. We do this as it's possible that the config file
specifies a lnddir, but it isn't actually used as the directory has
already been created.
