bpo-37335, test_c_locale_coercion: Remove unnecessary code (GH-14447)


Python initialization now ensures that sys stream encoding
names are always normalized by codecs.lookup(encoding).name.
Simplify test_c_locale_coercion: it doesn't have to normalize
encoding names anymore.
(cherry picked from commit 61bf97e91620e020939d57a36918ab22579920ff)
