    Install gpartedbin into @libexecdir@ (#85)
    
    Executables which are not intended for execution by users, but by other
    programs, should be installed into /usr/libexec [1][2].  gpartedbin
    falls into this category.  Update it's installation accordingly.
    
    Standard Autotools details: gpartedbin will be installed into
    EPREFIX/libexec by default.  To install gpartedbin into a different
    directory set libexecdir when configuring the build system.  Like this
    from git:
        ./autogen.sh --libexecdir=DIR
    or like this from tar release:
        ./configure --libexecdir=DIR

        "/usr/libexec includes internal binaries that are not intended to be
        executed directly by users or shell scripts.

        "libexecdir
        The directory for installing executable programs to be run by other
        programs rather than by users.  This directory should normally be
        /usr/local/libexec, but write it as $(exec_prefix)/libexec.  (If you
        are using Autoconf, write it as '@libexecdir@'.)
        "
    
    Closes #85 - Please install gpartedbin under /usr/libexec instead of
                 /usr/sbin
