RFR: 8001621: Update awk scripts that check output from jps/jcmd

[Staffan Larsen]

Some awk scripts in the tests check for 
-- process information unavailable 
as valid output. However, there are other outputs that are also 'ok'. For 
example: 
-- main class information unavailable 

webrev: http://cr.openjdk.java.net/~sla/8001621/webrev.01/


Thanks,
