Mark tests requiring network.

The Debian package build for pyshp failed because there is no network in the build environment.

The tests that download data need to be skipped, for this the network marker was added to test_reader_url().

Thanks for this! As the maintainer of the corresponding Fedora package, it helps me out too.

(Unfortunately, I have to resort to some ugly sed hackery to accomplish the same thing in the doctests, and I’m not sure how best to do that more cleanly in a way that I offer upstream.)

I chose to stop running those, now that a better test framework is also used. I considered adding a patch to strip out those examples, but considered it not worth the effort.
