RFR: 8238561 serviceability/sa tests continue to run out of memory on Win* machines

[Daniil Titov]

Please review the change [1] that ensures that VM and test options are forwarded to 
 j*-tools when they are launched from serviceability/sa tests.

In particular, it will ensure that passed to the tests maximum heap size settings ( -XX:MaxRAMPercentage) 
are also honored by  j*-tools serviceability/sa  tests launch.

The tests that expect an empty output  were corrected to ignore the product version printed 
in the error stream since in some  tiers the tests are run with ' -showversion' VM option.

Testing:  Mach5 tests for tier1 - tier7 passed.
