Disable failing libjingle_p2p_unittest test on Linux

I realize this diables 84 test cases and for all platforms, which
I'm not really comfortable with. I tried finding a better way but
couldn't without doing significant changes to the file.
I think the tests either needs to be fixed or otherwise refactored
in order to make more fine-grained disabling possible.

Another (too) large disabling was done by holmer@ in
https://webrtc-codereview.appspot.com/2227004 where he should only have
disabled them on Windows, if the failures in webrtc:2383 was all that
caused those flakes.
