rustPlatform.bindgenHook: use the correct Libsystem on the 11.0 SDK

[reckenrode]

Description of changes

While troubleshooting ipetkov/crane#329, I found that the 11.0 SDK rustPlatform.bindgenHook was propagating Libsystem from the 10.12 SDK (because the hook exports Clang’s nix-support/libc-c(xx)flags). Providing it with a wrapped Clang using the 11.0 SDK Libsystem resolves the issue.

Nice! I'll check if killport can migrate to rustPlatform.bindgenHook.

EDIT: It works!
