doom: Write -cdrom savegames to c:\doomdata.

When using the -cdrom command line parameter (does anyone still use
that?), savegames should be written to c:\doomdata to properly
reproduce Vanilla behavior. These were being incorrectly written to
c:\doomdata\savegames\foo.wad instead.

This fixes #175. Thanks Alexandre-Xavier.
