[PATCH v3 1/3] chcp: Add a stub application for changing the codepage.

[Erich E. Hoover]

v3: Fix makefile mistake in v2
v2: The executable is called chcp.com even though it's a PE file (thanks Zeb!)

Anaconda expects to be able to call chcp to get/set the console codepage.
Adding a stub application is sufficient to appease it.

Best,
Erich
