Andrew Childs 38207735f4 darwin/make-bootstrap-tools: move "lib" from install name to rpath
The rpath structure for the bootstrap tools was reworked to minimize
the amount of rewriting required on unpack, but the test was not
updated to match the different structure.

Additionally [1] builds that use the bootstrap version of libc++
cannot find libc++abi if the reference includes the "lib"
component (ie, libc++ refers to libc++abi with
@rpath/lib/libc++abi.dylib).

Test failure observed on Hydra: https://hydra.nixos.org/build/143130126
