Remove deprecated Glib::thread_init() (!22)

Browse source 
Use of Glib::thread_init() was deprecated in glibmm 2.32 [1].  The
oldest supported distributions have these versions:
    Debian 8           glibmm 2.42.0
    RHEL / CentOS 7    glibmm 2.56.0
    SLES 12            glibmm 2.38.1
    Ubuntu 14.04 LTS   glibmm 2.39.93

Checking further the glibmm 2.32 reference manual says this about
Glib::thread_init() [2]:
    Initializes the GLib thread system.

    Deprecated:
    Calling thread_init() is no longer necessary and no longer has any
    effect.

However only some of the glibmm example programs had Glib::thread_init()
removed, others had it replaced by Glib::init() [3].  Again the glibmm
2.32 reference manual says this about Glib::init() [4]:
    Initialize glibmm.

    You may call this more than once.  You do not need to call this if
    you are using Glib::MainLoop or Gtk::Main, because they call it for
    you.

GParted does call Gtk::Main and test_PipeCapture does call
Glib::MainLoop.  Therefore just raise the minimum version to glibmm 2.32
and remove both calls to Glib::thread_init().
