In the new-style testing configurations, we were hardcoding paths to the
`include` and `lib` directories, which was incorrect but always went
unnoticed because the hardcoded values always happened to match the
actual value.
When using new-style configs with the bootstrapping build, this falls
appart -- and we never noticed this because the bootstrapping build was
still using old style configs.
This patch removes the %{install} substitution, which makes it too
tempting to hardcode installation paths, and it also switches the
bootstrapping build to actually using new-style configs like we
always intended to do.

We added one for libc++ recently, and this patch adds one for libc++abi.
Also, as a fly-by fix, include older libunwind dylibs in the testing of
libc++ and libc++abi, which fixes some issues related to running
back-deployment tests on newer systems.

This testing configuration links tests against one libc++ shared library,
but runs them against another libc++ shared library. This makes sure that
we can build applications against the libc++ provided in a recent SDK and
back-deploy them to platforms containing older libc++ dylibs.
It also switches the Apple CI script to using that new configuration
instead of the legacy one.
