[kernel/tests/thread] Better error information + win9x fix

[Paul Vriens]

Hi,

some small changes. Doesn't make the test succeed on windows, but now we
show at least the correct error information.

Changelog:
  Corrected last error information
  Make sure we can run the tests on win9x

Cheers,

Paul.
