Isolate + swarm telemetry_unittest on all platforms

@dtu for changes to tools/telemetry/telemetry/internal/util/find_dependencies.py
& bootstrap_deps files.
These changes are due to the fact that boot_strap module in telemetry
making assumption about chromium directory containing "src/"
folder which isn't true in the context of isolated testing.
Since telemetry_dependencies_unittest.py uses find_dependencies
for checking that telemetry doesn't contain extra python
module deps, those changes are included to make
telemetry_unittests passing.
