flashrom.c: extract operation only uses layout files

This change fixes a bug on handling the extract operation. Extract
operation reads the layout regions to filenames with equal name to the
specified layout regions. read_flash_to_file() does this work via
write_buf_to_include_args(). This change makes the call to
write_buf_to_file() optional as it is still required for -r (read
operation) but not for -x (extract operation).
