ANDROID: Improve OWNERS file definitions

- Extend subdirectory expressions to also include recursively
- Combine expressions with common owners
- Minor cleanups

Note, the way expressions are evaluated in the code-owners plugin (as
of now and for compatibility with the `find-owners` plugin), means we
match slightly more than expected, even with just the single asterisk.
As expressions like `net*` are implicitly treated like `{**/,}net*`,
we would not only match net_something.h and net_filter/header.h, but
also (unexpectedly) platform/net_something.h.
This change does not make things better in this regards, but for all the
above mentioned points, this is an improvement.
