[Android] memory_inspector: move backends one folder up.

[Android] memory_inspector: move backends one folder up.

This simply moves the backends in backends/android up one folder.
The current naming structure was redundant and some of the classes
there are not really android specific. Moving up since there is some
work in progress to introduce support for other platforms, so it
doesn't make much sense to keep a folder named 'android'.
No functional change is intended.
