Fix action conflict errors from exec config / targetLibcTop mismatch.
Summary:
1. `host.targetLibcTopLabel = libcTopLabel` creates action conflicts with
exec configs.
2. This is because a top-level exec config inherits a different libcTopLabel than
one after, say, an Android split transition.
3. This doesn't break host configs since they all inherit the (pre-transition)
top-level config.
4. Since the intention of targetLibcTopLabel is to preserve the top-level config
for a temporary C++ toolchain hack, I've updated its semantics to guarantee that
more forcefully.
