[LTP] test.sh and ROD redirection

What about this one:

diff --git a/testcases/lib/test.sh b/testcases/lib/test.sh
index 074be74..ef2af14 100644
--- a/testcases/lib/test.sh

+		$@

 	if [ $? -ne 0 ]; then
 		tst_brkm TBROK "$@ failed"
 	fi


It's called as: 'ROD echo a \> b', the reason for choosing \> is that
the error message will contain '>' instead of some strange char as %.

I.e. doing 'ROD echo a \> /proc/cpuinfo' yields:

test.sh: line 235: /proc/cpuinfo: Permission denied
foo 1 TBROK : echo b > /proc/cpuinfo failed
