[PATCH 2/2] ucrtbase/tests: Add tests for __conio_common_vcprintf()/_vcwprintf()

[Piotr Caban]

Hi,

this tests will not work when there's no console window. It will break 
the tests under wine when running them this way:
wine ucrtbase_test.exe.so printf &>log

I think it's OK if we test only print functions that work on 
strings/file descriptors so we don't spam test output.

Thanks,
Piotr
