Revert of [Android] Add a java.lang.System wrapper. (patchset #2 id:20001 of https://codereview.chromium.org/1283543003/ )

Reason for revert:
This doesn't actually work.

Original issue's description:
> [Android] Add a java.lang.System wrapper.
>
> Add a basic JNI wrapper for java.lang.System. Expose just the
> getProperty() method, eliminating a deprecated __system_property_get
> usage as well as a seperate System.getProperty wrapper.
>
> The remaining uses of __system_property_get will be removed in
> https://codereview.chromium.org/1236283002/.
