    Accept reading shorter UUIDs from FAT16/32 file systems (!49)
    
    The tests were failing like this:
    
        $ ./test_SupportedFileSystems --gtest_filter='*CreateAndReadUUID/fat16'
    ....
        [ RUN      ] My/SupportedFileSystemsTest.CreateAndReadUUID/fat16
        test_SupportedFileSystems.cc:552: Failure
        Expected equality of these values:
          m_partition.uuid.size()
            Which is: 9
          36U
            Which is: 36
        [  FAILED  ] My/SupportedFileSystemsTest.CreateAndReadUUID/fat16, where GetParam() = 13 (45 ms)
    
    This is because the test was expecting a full 36 character UUID as used
    by Linux file systems.  Also accept shorter 9 character "UUID"s as used
    by FAT16/32 file systems.
    
    Closes !49 - Add file system interface tests
