Subject: simulator: Simulate external storage for HAVE_MULTIDRIVE.

The virtual external storage can be inserted/extracted with the e key. This
has little effect because there is no way to access the storage (yet, a later
commit will change this). Except on ondio where the mmc needs to be
extracted before entering USB (like on real target).
