Rename libunwind -> libunwind_shared

The LLVM build system produces a libunwind.a, and the Clang driver
links its libunwind.a automatically when -nostdlib isn't passed. I'd
like to keep the libunwind.a name, but adding a Soong prebuilt module
of name "libunwind" conflicts with the external/libunwind module that
practically no one is using.

Fix the conflict by renaming libunwind to libunwind_shared, and
removing unnecessary uses of the old module.

(Code should use libunwindstack.so to collect backtraces, and it should
use libc.so's _Unwind_* APIs for C++ exception handling unwinding.)

Test: build Android
