add CONFIG_VT_UNICODE 



As of now, the kernel defaults to non-unicode and XLATE for the keyboard.
We've been changing this in Fedora, but that requires patching the defaults
in the kernel.

The attached introduces CONFIG_VT_UNICODE, which sets the console in
unicode mode by default on boot, including both the virtual terminal and
the keyboard driver.

	  If you say Y here, the virtual terminal will be in UTF-8 by default,

	  This can also be changed by passing 'default_utf8=<0|1>' on the
