To prevent further confusion which is which, dbaccess
UserInformation already got that wrong since ever.

/org.openoffice.Setup/L10N/ooLocale is the UI locale.
/org.openoffice.Setup/L10N/ooSetupSystemLocale is the work locale.

Confusingly due to legacy when the setup program was a separate
binary that picked the UI ooLocale and later set up the default
(system) work locale as well.
