RFR: JDK-8170279: Langtools test/Makefile ignores failed tests

Wed Nov 23 12:29:30 UTC 2016

After JDK-8167354, when a test fails in jtreg, the langtools 
test/Makefile ignores the result and exits with 0. This causes (at 
least) JPRT jobs to not fail when langtools tests fail. The reason for 
this is the added "| tee" construct which overrides the exit value from 
jtreg.
