Set Locale to English when uppercasing strings to match Enums

Fixes https://github.com/bazelbuild/bazel/issues/5157

If a user's default system locale is not `en`, `en_US` or `en_UK`, there may be a chance that `String#toUpperCase` will result in a string that does not exist in the Enum declaration. This is the case in #5157.

To fix this, it's either

1) setting the Locale in the individual `toUpperCase` calls or
2) set Locale to English by default from `Bazel.java`.

I chose the first because it seemed less intrusive, but I'm open to suggestions.

Closes #5184.
