Use the non-LTO/PGO hwbinder in libmedia2_jni

Bug: http://b/119560349

Currently, any binary links in a PGO-enabled static library also needs
to opt into PGO.  With b/119560349, this should be done automatically by
the build system.  Until then, use the non-PGO version of libhwbinder in
libmedia2_jni.
