Add non-macro stdin/stdout/stderr too.
Various C and C++ standards explicitly say that stdin/stdout/stderr
should be macros, but glibc makes them global variables too. This
means it's possible to write code that uses those names as locals,
but that code (toybox being an example) won't build on bionic.
If we'd done this earlier, we could have hidden __sF for LP64, but
it's too late now.
