Logo (Builtin): Change WiiLinuxNgx to more generic name

Wii-Linux-Ngx is no longer the most up to date version of Linux for the Wii.
This change retains the original name for compatibility sake, and because
Neagix's version does indeed still exist.  It moves the ASCII art to a more
generic file path, and introduces 2 new aliases for it: Wii-Linux, and WiiLinux.
