Fix build/android/enable_asserts.py.

Fix build/android/enable_asserts.py.

The script seems to have been broken in
https://codereview.chromium.org/221823011 (missing device serial when
creating DeviceUtils).

This fixes the script by iterating over all connected devices.

build/android/enable_asserts.py:26: for device in
[device_utils.DeviceUtils(serial) for serial in devices]:
I think it'd be good to have this optionally accept a serial number and only
enable assertions for that device if it's present. I'm ok with you TODOing me on
that if you don't want to do it in here, though.

I should mention that my lgtms don't count (yet), so Craig should still look at
this.
