    Fix configuration version compare issue affecting libparted from GIT (#753525)
    
    When configuring GParted build with libparted from GIT it may perform
    the version compares incorrectly and think the version of libparted is
    higher that it actually is.  Libparted uses the number of commits from
    the last git tag as the third part of the version number.
    
    For example install libparted from one commit before release 3.1, 142
    commits after release 3.0.
        $ git checkout v3.1^
        $ describe
        v3.0-142-g82327a3
        $ ./bootstrap
        $ ./configure --prefix=/tmp/parted-3.0-git
        $ make && make install
    
    Configure GParted:
        $ export CPPFLAGS=-I/tmp/parted-3.0-git/include
        $ export LDFLAGS=-L/tmp/parted-3.0-git/lib
        $ export LD_RUN_PATH=/tmp/parted-3.0-git/lib
        $ export PKG_CONFIG_PATH=/tmp/parted-3.0-git/lib/pkgconfig
        $ ./configure
        ...
        checking for libparted >= 1.7.1 (querying pkg-config)... 3.0.142-8232
        checking for 2.0 <= libparted <= 3.0 (loop table creation doesn't delete old partitions)... (cached) 
no
        checking for libparted >= 2.2 (improved pt re-read)... (cached) yes
        checking for ped_file_system_resize in -lparted... no
        checking for ped_file_system_resize in -lparted-fs-resize... yes
        checking for libparted >= 3.2 (online resize)... (cached) no
        ...
    Libparted is reported as version 3.0.142, but checking of the version
    between 2.0 and 3.0 inclusive fails.
    
    The configure script is multiplying components of the version by 100
    when adding them together.
        $ echo 3.0.142-8232 | awk -F. '{print $1 * 10000 + $2 * 100 + $3}'
        30142
    
    So it is only allowing up to 99 commits before it is equivalent to the
    second minor number increasing by one.  Increase the multiplication
    factor to 10000, allowing up to 9999 commits between releases.  An order
    of magnitude more commits than so far seen between parted releases.

                 non-released versions of libparted
