RFR: JDK-8208468: [TESTBUG] nsk/jdb/locals/locals002: fails with "Prompt is not received during ... milliseconds"

[Alex Menkov]

+1 for the fix as a temporary workaround.
Actually that's look a bit strange as debuggee output is redirected.
So I'd expected it does not go through jdb log, and it should appear in 
the test log with "debuggee.stdout>" prefix.
