Define SK_USE_FREETYPE_EMBOLDEN on Android

(From https://codereview.chromium.org/411313002/ by h.joshi@samsung.com:
Colored Emoji not drawn in Chrome if font style is set as Bold.
When Bold font is asked, then Skia try to generate image/bitmap from
path (if Bold font is not present) which is not correct case for Colored
Emoji bitmap font.)

Define SK_USE_FREETYPE_EMBOLDEN to prefer FreeType's emboldeing
algorithm to Skia's.

Can we combine this with "SK_BUILD_FOR_UNIX"?

Done.

I wonder if the SK_CPU_BENDIAN section still applies, since we no longer have
bitmap_platform_device_linux.h.
