draw: remove Go 1.8 support

This change removes support for Go 1.8 and older, as they're no longer
supported per release policy¹.

This brings back a simpler file layout that was here prior to CL 36730,
but keeps using type aliases for the exported names from the standard
library's image/draw package.

Don't keep the comment motivating type alias use, since that feature is
no longer new, and commonly understood by now.
