test: fix deadlock on windows when running tests

The deadlock was caused by setting stdout behavior to ignore, when
spawning the patch command.  When the patch command writes to devnull it
causes some errors and a deadlock.

The cause of the bug is probably Zig using `\Device\Null` from `ntdll`
while git-bash uses `NUL` from `kernel32`.
