Copy NetworkNotificationManager resources to conectivity module.

The localized resources were automatically generated with:

===========
export OLDRES=core/res/res
export NEWRES=packages/Connectivity/service/ServiceConnectivityResources/res
export FILE=services/core/java/com/android/server/connectivity/NetworkNotificationManager.java

for i in $OLDRES/values-*/strings.xml; do
    outfile=$NEWRES/${i#core/res/res/}
    outdir=$(dirname $outfile)

    if egrep -q "$regex" $i || egrep -q "$strarrayregex" $i; then
        mkdir -p $outdir

        cat << EOF > $outfile
<?xml version="1.0" encoding="utf-8"?>

        egrep $regex $i >> $outfile

        egrep -A $strarraylines "$strarrayregex" $i >> $outfile

        echo "</resources>" >> $outfile
    fi
done
===========

The text to the the base resources file was added manually from
the output of:

===========
egrep -B 2 $regex core/res/res/values/strings.xml  | grep -v -- ^--
egrep -B 2 -A 6 $strarrayregex core/res/res/values/strings.xml  | grep -v -- ^--
===========

The drawables were copied from the Wifi resources and from the
framework resources.
