Query style from asset-created font (Minikin)

This patch sets fStyle on the TypefaceImpl based on querying the font,
which is important in the Typeface.createFromAsset path. This fixes both
the style returned from getStyle() and also selects fallback fonts to
best match the style of the main font.

Fixes bug 15429916: "Typeface.getStyle always returning 0 in some L
devices".
