[PATCH] libc++: add NaCl and PNaCl support for std::random_device

Your changes look good; but now I'm wondering if you want to accept both `"/dev/random"` and `"/dev/urandom"` as valid tokens.
Now I'm wondering what bozo checked in the windows implementation w/o noticing that it broke this test on Windows. Oh - that was me.
Should the windows implementation also accept only `"/dev/random"` and `"/dev/urandom"` as valid tokens?
That would enable us to make the test portable; and help people to write cross-platform code.

I don't think you need to actually set `_LIBCPP_USING_NACL_RANDOM` to a value.

I don't really like this; it's leaking implementation information into the test framework.
