Update TestExpectation to prepare for ICU 52 upgrade

Update TestExpectation to prepare for ICU 52 upgrade

ICU 52 has slightly different date time format for a lot of locales 
including en-US. A comma was added between date and time in en-US.
In https://codereview.chromium.org/302323004, I made a necessary adjustment
to TestExpectations, but forgot to list the following test as requiring
a manual rebaseline.

fast/forms/datetimelocal/datetimelocal-appearance-basic.html

In addition, add back 'Android' for a few tests that require manual 
rebaselining after ICU 52 update.

BUG=378919, 132145
TEST=datetime* tests passed as expected (fail or pass).

I'm TBR'ing this CL because the ICU update CL (
https://codereview.chromium.org/265613002/ ) is about to be landed.
