[gparted/psusi/refactor: 15/16] Combine duplicate code for ext[234]



commit 77a6b002315cecf13d0ad11c9619cea4d82b453d

    Combine duplicate code for ext[234]
    
    There were separate modules for ext3 and ext4 even though there
    were virtually no differences with ext2.  Remove the duplicate
    modules and patch ext2 to serve as a common reference for all
    three sub types.
