cmd: Use OEM code page when reading a file.

Calling GetConsoleCP() when ReadConsoleW() fails (potentially indicating that cmd.exe's instance isn't attached to a console) makes no sense. In details, since GetConsoleCP() returns 0 when not attached to a console to indicate error, we're in fact using CP_ACP. So fallback explicitely to OEM CP (which is the default for CUI programs).
