Disable mcrouter when building HHVM with libc++

[Atry]

mcrouter is using folly/concurrency/AtomicSharedPtr.h, which does not support Clang according the comment at https://github.com/facebook/hhvm/blob/156a77d5a301033200601ddefb4dcaf26eb1ff9c/third-party/folly/src/folly/concurrency/detail/AtomicSharedPtr-detail.h#L28-L34

Test Plan:

Without this PR

Without this PR, mcrouter will fail:
