[Bug 1348530] [NEW] "USB Floppies" a not mounted using $FATFS

[Jens Reimann]

Public bug reported:

The the CD-ROM detection tries to find a USB stick image and mount it as
a base for installation.

For this the tools iterates over all found devices and tries to mount
them. For cdrom devices is of course uses "$CDFS" and for "usb
partition" is tries $CDFS and $FATFS.

But for "usb floppies" is only tries $CDFS, which is ok if an ISO image
was written to a USB stick, but if a bootable FAT image directly gets
installed to the USB stick (without partions, as some image writers do
it), then the installer will boot and not find "a CD ROM" since "USB
Floppies" are not tried via "$FATFS". Which is odd since floppies would
most likely be "$FATFS".

This is all happening in the main loop (while true). Either the first
"for" loop gets enhanced to also try and mount "$FATFS" or gets merged
with the following "for" loop, which already checks both ways.
