Show flag when detect_spelllang is 'flag', do not when it is 0.

927e142e94 broke the "show the lang flag"
functionality, as the check `if g:airline_detect_spelllang` is always
false when this variable is `'flag'`. Explicitly check whether this
variable is the string `'0'` to detect whether the feature should be
disabled.
