This reverts commit e22f99743b4f0bea4a9b8e7703ce5ffbfda37a04.
Adding the exit(exitCode) fixes the hang.
Tested by running `fx run-host-tests` with a topaz checkout.
Verified the hang before, no hang after.
This reverts commit 032f8cdb8b563bdc200acdce068945a834bf2271.
The test runner hangs on exit after all tests pass when trying
to roll this into Fuchsia.
Previously, the usage analytics would generate a write to the user's
HOME directory during the Fuchsia build. We're tightening down the
environment in which we run the Fuchsia build, and these writes are now
more obvious.
This patch removes the usage analytics during the Fuchsia build,
avoiding the write to the user's HOME directory.
