Exclude libperfetto_hprof library from golem tarball

The presence of this library initializes a plugin which slows the
initialization of the runtime and means many benchmarks fail to
achieve expected CPU utilization (and are subsequently rejected as
invalid).

Bug: 129332183
Bug: 147577567

Test: Run golem benchmarks on 32-bit ARM SBC with and without library
      in out/ directory.
