Fix building when Gtk doesn't support version check

[markvoorhies]

This is a quick patch to fix a build problem that I ran into this morning when updating matplotlib via pyston on my Ubuntu 12 laptop. I haven't dug into this deeply, but this
is my current understanding (and the patch does fix the build problem on my laptop):

python setup.py install --user
fails with
AttributeError: 'gi.repository.Gtk' object has no attribute 'get_major_version'

for old versions of Gtk without support for introspection
(specifically, on Ubuntu 12 with python-gtk2 2.24.0-3)

This commit silently drops the associated exceptions for the two Gtk
version checks in setupext.py

Thanks @markvoorhies. LGTM 👍

Thanks. Something is fishy here, since its requesting gtk3, the gtk2
version shouldn't enter into it... I'Ll have a look next week.

@markvoorhies, I suspect you don't actually have the full gtk3 dependencies installed. It works on my Ubuntu Precise VM. I suspect this is the version of Ubuntu you have. Have you installed the python-gobject package? It should pull in python-gi and python-gobject-2, and I think that is what it takes.

Sorry for not notating this earlier, but I think this is a duplicate of #1949. @markvoorhies: can you confirm that resolves the issue. #1949 explicitly says "I want Gtk 3 when using gobject introspection" -- it therefore should guarantee that the new version-getting API is there.

@mdboom Looks like that fixed it =)

Matplotlib 9e734b6 builds and runs while the build error reproduces for 9e477b3.

@efiring yep, the laptop is Ubuntu Precise amd64:
