16k: bionic: Re-align libtest_empty.so to 16kb for arm64 and x86_64
This is required as the first step to getting several bionic test suites
to pass for 16k page size targets.
Command used to generate files:
```
$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++
-O2 -shared -fPIC
-o <output path>
--target=<aarch64-linux-android29 OR x86_64-linux-android29>
-B $NDK/toolchain/llvm-project/llvm/tools/gold
-Wl,-z,max-page-size=16384
libs/empty.cpp
```
