Remove __INTRODUCED_IN for obsolete API levels.
The NDK only supports >= 16, so remove anything older than that to avoid
giving the misleading impression that such old targets are still
supported.
(This change doesn't touch <unistd.h>. I'll follow up with that once the
outstanding FORTIFY changes to that file are in.)
Test: builds
