Fix STDISK offset for strife

Introduce some static variables for the x and y offset for drawing
STDISK and initialise them with I_EnableLoadingDisk. Pass the right
arguments for Doom and Strife in the relevant calls.

The disk is now drawn in the top-right for Strife, matching the
behaviour of the DOS version.
