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

Browse Source 
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.

Using ``<filesystem>`` and libc++fs
====================================
Libc++ provides the implementation of the filesystem library in a separate
library. Users of ``<filesystem>`` and ``<experimental/filesystem>`` are
required to link ``-lc++fs``.

Prior to libc++ 7.0, users of ``<experimental/filesystem>`` were required
to link libc++experimental.
.. warning::
The Filesystem library is still experimental in nature. As such normal
guarantees about ABI stability and backwards compatibility do not yet apply
to it. In the future, this restriction will be removed.
