bpo-29571: Fix test_re.test_locale_flag() (GH-12099)
...
Use locale.getpreferredencoding() rather than locale.getlocale() to
get the locale encoding. With some locales, locale.getlocale()
returns the wrong encoding.
For example, on Fedora 29, locale.getlocale() returns ISO-8859-1
encoding for the "en_IN" locale, whereas
locale.getpreferredencoding() reports the correct encoding: UTF-8.

``local.getlocale(locale.LC_CTYPE)`` and

in some cases (such as the ``en_IN`` locale).
``re.LOCALE`` uses the latter, so update the test case to match.
