RFR: 8238373: Punctuation should be same in jlink help usage on Japanese language [v2]

[KIRIYAMA Takuya]

> When showing help for the jlink command in a Japanese locale, delimiters of option's aliases are a mixture of "," and \u3001. Delimiter should be unified to ",".
> As the same, there is a inconsistency of delimiters in the jar command help in a Japanese locale, and "," should be used.
> Similarly, the javap command help uses space as delimiters other than the module option in all locales. This inconsistency should also be corrected.
> 
> Would you please review this fix?
