feat(shim): implement stream_select/stream_set_blocking via libc

Add fcntl/select extern "C" declarations and a PhpResource::raw_fd seam so the
symfony Process pipe loop can read a live child's stdout/stderr. Fix fread on a
non-blocking fd (WouldBlock -> "") and the Process null-cwd default. Real
subprocess output capture now works; un-ignore the process_executor tests.
