Switch to testing ext2 interface via SupportedFilesystems class (!49)

Replace directly using ext2 derived FileSystem interface class with
using the SupportedFileSystems class.  This is a step in getting ready
for testing all the GParted file system interface classes in one go.

Closes !49 - Add file system interface tests
