config.h: fix incorrect defines for _wopen()

This is a regression from commit

  01341840 ("add basic CMake based build")

S_IRUSR and S_IWUSR should NOT be defined as 0 but
as _S_IREAD and _S_IWRITE, as it was already fixed in commit

  077445d0 ("Fix some more wrong defines in config-msvc.h")

Those are used as permission mode when opening a file. Passing
zero makes file read-only, which break for example --status-file
functionality.
