Disable network_service_interactive_ui_tests, network_service_content_browsertests on ToTLinuxTSan

interactive_ui_tests and content_browsertests have extra shards on TSan,
but the network_service_ versions don't since they're disabled on the main
TSan bot for resource reasons. Rather than giving them more shards on the ToT
bot, make the ToT bot more like the main TSan and disable these two test suites
there too.

network_service_interactive_ui_tests used to take 30 min to run in the current
setup, network_service_content_browsertests took 45 min.
