If a subprocess spawned with CREATE_NEW_CONSOLE creation flag fails with STATUS_DLL_INIT_FAILED return code, skip the test. It's likely a memory allocation failure in the desktop heap memory which caused the DLL init failure.

(cherry picked from commit e8034dd)

Sorry, @vstinner, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.
