Revert "[libc++] Build <filesystem> support as part of the dylib"

When I applied r356500 (https://reviews.llvm.org/D59152), I somehow
deleted all of filesystem's tests. I will revert r356500 and re-apply
it properly.

-* rXXXXXX - Integrate <filesystem> support into the shared library
-
-  This patch introduces support for <filesystem> into the shared library,
-  instead of requiring users to manually link against a static archive. As
-  such, new symbols required to implement <filesystem> are exported from
-  the shared library.
