Fix SysStrings unit test failure on Chromecast
Chromecast has a utf8 locale, and all calls to setlocale with non-NULL
locale name fail. Some of these issues were addressed previously in
https://codereview.chromium.org/790903003/
but we still had failures remaining in SysStrings unit tests, in
particular ScopedLocale was failing to set the locale.
