Try to look for the new name in the process's namespace before falling back
to the old one (and giving up on CD-ROM detection if everything falls apart).
iOS has PHYSFS_NO_CDROM_SUPPORT defined, so this isn't used there.
It's not really "macOS," it's all of Apple's platforms (iOS, watchOS,
tvOS...AppleCarOS? heh), and second...we're about to need access to Cocoa
APIs, so we need it to be Objective-C. I fought as long as I could. :/
