[OE-core][kirkstone 31/31] base-passwd: Disable shell for default users

[Steve Sakoman <steve@sakoman.com>]

From: Davide Gardenal <davidegarde2000@gmail.com>

Change the shell of all global static users other than root (which
retains /bin/sh) and sync (as /bin/sync is rather harmless) to
/sbin/nologin (as /usr/sbin/nologin does not exist in openembedded)
