[fix] babel-plugin only rewrites paths for known modules

Don't rewrite import paths for non-existent modules or types. They will
attempt to be imported from the package's main export. This change
currently requires a module map to be generated for the babel-plugin to
use. The map is automatically regenerated for any commit that alters the
entry file of react-native-web.

Fix #822
