logging: Fix gpgrt_log_get_fd for file.
* src/logging.c (fun_writer): Only use this for socket writing. (set_file_fd): Use es_stderr when "-". Use the stream by _gpgrt_fdopen when FD is specified. Use the stream by _gpgrt_fopen when name is not socket. Only use the stream by _gpgrt_fopencookie for socket. [HAVE_W32CE_SYSTEM]: Remove W32CE support.
