test.sh: tst_resm and tst_brkm enhance

If the output information is too long, we need a newline.
But tst_resm and tst_brkm only prints $1 and $2.
This patch will make them print all parameters.

For example:
In <LTP>/testcases/network/multicast/mc_cmds
--------------------------------------------------------------------------------
            ...
113         ping -c2 -I $INTERFACE 224.0.0.1 > $PING_OUT
114         if [ $? -ne 0 ]; then
115                 tst_resm TINFO "Trying to ping with $INTERFACE_DEVICE"\
116                                "with the -I option instead of IP address"
                    ...
122         fi
            ...
--------------------------------------------------------------------------------

If "ping -c2 -I $INTERFACE 224.0.0.1 > $PING_OUT" failed,
it just output "Trying to ping with $INTERFACE_DEVICE",
"with the -I option instead of IP address" would be discard.

After this patch, if "ping ..." failed the second string also output.
