Update WebAudio layout tests for Android (arm32)
Update thresholds and print precision appropriately so that these
tests pass on Android.
The audiobuffersource-loop-points test differs by at most 1 bit in
the original reference so we're just adding an Android-specific result.
These tests were run on a Galaxy Nexus and pass there.
