Fix of PrusaSlicer trying to access my floppy disk (A:\)

Browse Source 
Some customers seem to posses a floppy drive (sic!) and some floppy
drives start spinning if accessed just to check whether there is
a medium plugged in or not.

From now, the A: and B: drives are not checked anymore for removable
media. Now let's pray nobody maps an SD card or flash drive to A: or B:
