[gparted] Increase minimum required libparted to 2.2 (!22)

[Curtis Gedak <gedakc src gnome org>]

commit 8df975c7d1b5d69897f286bfc5574c51cf58c9d5

    Increase minimum required libparted to 2.2 (!22)
    
    Raise the minimum required version of GNU Parted from 1.7.1 to 2.2,
    released 2010-02-16 [1][2].  The oldest supported distributions, also
    with gtkmm >= 2.24, since commit [3], are:
        Debian 8           parted 3.2
        RHEL / CentOS 7    parted 3.1
        SLES 12            parted 3.1
        Ubuntu 14.04 LTS   parted 2.3
    
    Raising the minimum required version allows removal of optional code
    associated with these definitions:
    *   USE_LIBPARTED_LARGE_SECTOR_SUPPORT
        Fallback code reporting ignored device with logical sector size
        other than 512 bytes.
    *   ENABLE_PT_REREAD_WORKAROUND
        Fallback code re-attempting to inform the kernel of partition
        changes.
