Remove all duplicate platform files, i.e development/ndk/platforms/android-N now
only contains files that are introduced in API level 'N' and not found in level 'N-1'
(This makes it easier to manage independent platform release branches, and makes
platform additions trivial to examine and maintain).
Move samples that depends on features of API level 'N' into platforms/android-N/samples
+ update tests/run-all.sh accordingly

The idea is to allow developing the NDK in the open, while
having the platforms and samples under a private branch until
the corresponding release are open-sourced.
