hush: implement getopt builtin ...

Positional parameters are not nice, so implement a getopt
function. This has to be done as a builtin because otherwise
we have no access to the parents argc/argv.

getopt works as expected, here is a little example:

while getopt "hs:" OPT
do
        if [ $OPT = h ]; then
                echo "usage"
                exit 1
        else
                echo "scr: opt: $OPT optarg: $OPTARG"
	fi
done

hush: Fix return code when calling 'exit' inside loops ...

v2: Do not exit from all scripts but only the current one

This fixes the case:

barebox:/ cat /test
if [ 0 = 0 ]; then
	exit 1
fi
barebox:/ /test
barebox:/ echo $?
0
barebox:/

Also, remove code to not allow exit from main shell. The for(;;) loop
in common/startup.c will bring us back anyway.
