Fix creation of system users after sysupgrades 

The ar71xx-tiny target sets CONFIG_CLEAN_IPKG, which would delete opkg
control files required for user creation. Fix image generation and the user
creation script.

Fixes #1012

Subject: include/rootfs.mk: keep Require-User lines with CONFIG_CLEAN_IPKG
Require-User is handled by /etc/uci-defaults/13_fix_group_user on first
boot, so we need to keep these when removing all opkg data with
CONFIG_CLEAN_IPKG.

Subject: base-files: fix user creation on sysupgrade with few opkg control files
If only a single opkg control file exists (which can happen with
CONFIG_CLEAN_IPKG), grep would not print the file name by default. Instead
of forcing it using -H, we just switch to -l (print only file names) and
get rid of the cut.
Add -s to suppress an error message when no control files exist.
