[gparted] Further RHEL / CentOS 5.9 compile fixes (#695279)

[Curtis Gedak <gedakc src gnome org>]

commit 5f06ea33698791cfd77f1d7607e73bed00d058d0
Author: Mike Fleetwood <mike fleetwood googlemail com>

    Further RHEL / CentOS 5.9 compile fixes (#695279)
    
    Glib::ustring::compose() method requires glibmm >= 2.16, but RHEL /
    CentOS 5.9 only provides glibmm 2.12.  Replace with String::ucompose()
    as is used everywhere else in the code.
    
    Add missing include for kill() and SIGINT declarations.
    
    Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
