Fix windows failure on InternalDistributionArchiveSetupPluginFuncTest

[Poojita-Raj]

Signed-off-by: Poojita Raj poojiraj@amazon.com

Description

Failure on windows for the InternalDistributionArchiveSetupPluginFuncTest is unexpected. Fails with "registered distribution provides archives and directory variant".
This is because -

tar task execution is skipped on windows.
plain copy task execution doesn't execute on windows since source files will not be present.

To get the test passing again, we check for expected conditions on windows and non-windows machines.
