Revert of Android: Use linker script to hide all non-JNI symbols (patchset #4 id:60001 of https://codereview.chromium.org/2633593004/ )

Reason for revert:
Speculative revert, potential culprit for webkit_tests crashing on "WebKit Android (Nexus4)".

Stack traces show not much else than JNI managed->native transitions and syscalls.

Original issue's description:
> Android: Use linker script to hide all non-JNI symbols
>
> The linker script is applied to all shared_library() targets by default,
> just like the hide_jni one was.
>
> This reduces the size of libchrome.so by 220kb.
