Exclude libjingle_p2p_unittest tests failing TSan Race verifier.

These tests have been failing for a long time at
http://build.chromium.org/p/client.webrtc.fyi/builders/Linux%20TsanRV
This bot runs a tool called TSan Race Verifier.
More info about Race Verifiers can be found at
https://code.google.com/p/data-race-test/wiki/RaceVerifier

By excluding the tests like this, they will also be disabled
for the normal TSan bot, where they currently pass. This shouldn't
be a problem since we have a TSan v2 bot running too (which uses
a different set of suppressions), so it should catch any newly
introduced race conditions. The TSan v2 bot will soon replace the
old TSan bot, as v1 is being deprecated.
