RFR: 8269373: some tests in jdk/tools/launcher/ fails on localized Windows platform

[Masanori Yano]

Hi all,

Could you please review the 8269373 bug fixes?

These tests call java.lang.ProcessBuilder in direct, so not used jtreg command option. To run non-localized tests, -Duser.language=en and -Duser.country=US options should be added in ProcessBuilder.
