Reorder static libs to appease ld.gold linker

Bug: http://b/112277682
Bug: http://b/79419131

Lld, which is the default linker for the platform, is able to resolve
symbols across libraries irrespective of the order they appear in the
command line.  This was not the case for ld.gold and other linkers.
Unfortunately, there are some targets that still rely on ld.gold
(pgo-taimen-config1 in internal release branch being one of
them).

With http://aosp/721652, libbt-stack should be added before libbt-common
so MessageLoopThread::~MessageLoopThread is resolved correctly.  If not,
the following error is reported by gold:

system/bt/stack/btu/btu_init.cc:41: error: undefined reference to
'bluetooth::common::MessageLoopThread::MessageLoopThread(std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char> > const&)'

Test: m USE_CLANG_LLD=false
