Add std::locale::global to list of locale dependent functions in lint-locale-dependence.sh.
We currently flag setlocale(...) as locale dependent, but prior to this commit we didn't flag
std::locale::global(...) as such.
In addition to setting the global C++ locale std::locale::global(...) also does the equivalent of std::setlocale(LC_ALL, ...);.
Thus the functionality of std::locale::global(...) is a superset of setlocale(...) :)

@laanwj Would you mind reviewing? You've shown interest in lint-locale-dependence.sh in the past (#13041) :)
ACK 54b5eb2b149a1f2a4a1dbdb9e0648c5a390d8e22, fine with me
Anything left to do here? :)
