Make Build.TYPE and Build.FINGERPRINT consistent for apps.

Some apps (namely Android Wear) like to do comparisons between TYPE and
FINGERPRINT and throw errors on inconsistencies. As our fingerprints are
almost always taken from stock ROMs, they don't really match our builds,
causing said comparisons to fail. Avoid those failures by taking build
type out of fingerprint for apps.
