ndk: x86: Update libc.so and libstdc++.so

This patch updates the system C and C++ libraries used for
the x86 ABI. We remove the old binary targetting API level 5

generated from the AOSP tree with the full_x86-eng build product.

This is necessary to be able to prebuild STLport binaries for
the x86 NDK.

The binaries corresponding to the AOSP platform/bionic.git tree
using the following SHA-1, when building full_x86-eng:
