Android: Remove sdk and sdk_path options

Since we are not building with Android Studio, using its sdk rather than
the checked-in one at //third_party/android_tools/sdk greatly improves
the editing experience and reduces issues using newer version of Android
Studio.

We no longer test with any --sdk-path or --sdk other than the default,
so rather than leaving the option untested, explicitly remove it.
