Reland of [Android] Make the test runner terminate gracefully on SIGTERM.

Reland of [Android] Make the test runner terminate gracefully on SIGTERM. (patchset #1 id:1 of https://codereview.chromium.org/2511243005/ )

Reason for revert:
After looking at that bot further, it's been failing occasionally w/ similar issues for a while.

e.g.
https://build.chromium.org/p/chromium.webkit/builders/Android%20Builder/builds/97567
https://build.chromium.org/p/chromium.webkit/builders/Android%20Builder/builds/97523
https://build.chromium.org/p/chromium.webkit/builders/Android%20Builder/builds/97482
https://build.chromium.org/p/chromium.webkit/builders/Android%20Builder/builds/97481

I'll investigate that separately, but in the meantime, I'm relanding this.
