Add elevation_service as deps

For some reason, our tests started to failed to compile.
https://ci.chromium.org/p/chrome/builders/ci/win-live-tests-builder-rel/4249
No related changes found.
My only guess is that: before, it first compile browser_tests, then
sync_integration_tests. After, it first compile sync_integration_tests,
and report error.
To repro the error on Windows:
1 gn clean out\Default
2 autoninja -C out\Default sync_integration_tests
