run_tests: Make sure a chroot exists before starting tests.
If run_tests was run (without --network) and no chroot existed, it
would hang while trying to download files needed to create the chroot.
So... make sure the chroot exists before disabling networking.
BUG=chromium:482108
TEST=Ran tests with/without existing chroot.
