RFR: 8361751: Test sun/tools/jcmd/TestJcmdSanity.java timed out on Windows

[Alex Menkov]

Tests which run serviceability tools to attach to the main test process can get deadlock with streaming output (see #24672 )
The fix disables attach streaming output for tests in jdk/sun/tools/jcmd

Testing: tier6, tier7
