Include <string> and <istream> outside __pnacl__.
Fixes webrtc/ Debug build with libc++ which failed to link std::getline
as this is defined in <istream>. <iostream> causes static initializers
and shouldn't be necessary.
Also adds to README.chromium that the overrides are used too get rid of
static initializers and to build on libc++.
