[AD] setup.c fails to compile with --disable-ossdigi

[Elias Pschernig <elias@xxxxxxxxxx>]

"Mr_Bones_" gave me the attached patch in #allegro to fix it. I didn't
follow that driver constants change (I guess, in prior allegro versions,
DIGI_OSS wouldn't have been defined if OSS was not available), so not
sure this is the right way to fix it.
