fix: crash caused by app.getLocaleCountryCode() (#32256)

Browse Source 
CFLocaleGetValue() returned null and crashed the process when
app.getLocaleCountryCode() was run on a CircleCI metal resource class
macOS instance with Xcode 12.5.1. This change fixes that logic and adds
further checks to make the code future-proof.

Here too people are complaining that the returned country code migth be
null: https://stackoverflow.com/questions/15202454/nslocalecountrycode-returns-nil
