Adding telemetry dep to the captured sites test target.

The captured sites test uses Web Page Replay Go (WPR Go) to replay
captured sites traffic. The captured sites test bots uses a script in the catapult project
to download WPR Go binaries. At the moment these bots are failing to
download WPR Go, presumably because bots' gn isolate is missing
references to the catapult project. This fix attempts to address this
problem by following the example of existing perf/telemetry test targets
in src/chrome/test/BUILD.gn and adding a dependency to the
telemetry_chrome_test_support target.
