Why is this needed? GN doesn't use isolate files, instead it uses data sections
which get converted to isolate files during runhooks transparently. I kind of
expected we'd delete all the .isolate files once GN is used everywhere. This
seems to contradict that goal.

See https://bugs.chromium.org/p/chromium/issues/detail?id=589318#c8

Android actually uses the .isolate files two different ways, unfortunately, and
GN/MB currently only addresses one of them. We will eventually need to fix the
android test scripts and/or MB to also address the other, but we need to do this
in the meantime to make swarming at least kinda work.
