Update path to Android font config file

In version LMP, Android is expected to change the path to their font
configuration file (and condense several files into one), as well as
changing the format (qv http://crrev.com/446473003/). This patch tries
the new path before falling back to the old path.

The new fonts are incompatible with assumptions made by the old
SkFontConfigInterfaceAndroid, so this patch MUST NOT land until
https://crrev.com/462073002/ or the equivalent has turned on the
new SkFontManager.
