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

[Gary Adams]

The print statements in the locals002 test have been observed to interfere
with the output from commands, replies and prompts used in the 
synchronization
of operations between the debugger and debuggee. This change will remove 
the
print statements. A follow up bug will be filed for longer term 
investigation of the
character at a time output which leaves a larger window for the output 
interruption
that occurs.
