[runtimes] Add tests for installation properties for vanilla configurations

[ldionne]

This patch adds tests for a few properties of the installation of libc++ in
the upstream LLVM configuration. We already have installation property
tests for specific vendor configurations, but it also makes sense to have
such tests for the configuration used by the LLVM release.
