Dan Albert 2610a328ce Filter REL out of preview codenames. 
Relanding https://r.android.com/2773148 in a different way, since
removing REL from ALL_CODENAMES prevents -next builds from booting
(see the comment for the code that relies on this behavior).

This reverts commit d637190deb.

Bug: http://b/303087088
Test: m ndk # with barbet-next-userdebug in goog/main
