RFR: 8311081: KeytoolReaderP12Test.java fail on localized Windows platform [v2]

[Justin Lu]

> Please review this PR which addresses `KeytoolReaderP12Test.java` failing for non-English locale users.
> 
> This test checks output from keytool, but fails on finding the value 'alias name' for non-English locale users. This is because 'alias name' is a localized value. (For example, in `ja` this is '別名'). 
> 
> To fix the failing issue, the keytool process should be ran with `-J-Duser.language=en -J-Duser.country=US`.
