    Add lookup for Linux kernel names of mountable file systems (#742741)
    
    Function Utils::get_filesystem_kernel_name() returns the name of the
    file system as needed for use in the mount command:
        mount -t TYPE DEVICE DIR
    
    Needed because the kernel / mount name is 'hfsplus' where as libparted /
    GParted, as reported by Utils::get_filesystem_string(), calls it 'hfs+'.
    So far just added debugging when mounting a file system to test the
    function works.
    
        # ./gartedbin
        ======================
        libparted : 2.1
        ======================
        DEBUG: (hfsplus) # mount -v /dev/sdb5 "/mnt/5"
        DEBUG: (nilfs2) # mount -v /dev/sdb1 "/mnt/1"
    
    Bug 742741 - Nilfs2 file system is unusable on RHEL/CentOS 6
