patches/openwrt: disable root account

This disables root account.

Placing of this patch expects it to be caried for a long time so it was
moved to second possition while current second patch was moved to thid.
That makes it of same number as existing patch but that patch is going
to be dropped in future so no harm to have them with same number for
now.

+Subject: [PATCH] base-files: disable root account
+
+In default on Turris OS configuration should be done through Foris to set
+all passwords (that includes Foris as well as system one if user
+chooses). This means that root login has to be disabled. This changes
+default to be so.
