KUDU-3474: Add zlib as dependency of libunwind for ARM

On ARM, libunwind includes support for compressed
.debug_info sections if zlib is available during
compilation. This means that libunwind can require zlib
at link time, but only for ARM architecture.

This modifies the build to add a zlib dependency for
libunwind if the architecture is ARM. It also reorders
the thirdparty build so that zlib is built before
libunwind. This is not strictly necessary, but it means
that libunwind would consistently have support for
compressed .debug_info sections on ARM. This does not
impact x86_64.

Testing:
 - Ran an ARM build on Ubuntu 20.04
