libstdc++: Adjust expected locale-dependent date formats in tests

The test 27_io/manipulators/extended/get_time/char/2.cc expects that
%a in the de_DE locale is "Di" but on FreeBSD it's "Di." with a trailing
period. Adjust the input string to be "1971 Di." instead of "Di 1971"
and that way if %a doesn't expect the trailing '.' it simply won't
extract it from the stream.

This fixes:
FAIL: 27_io/manipulators/extended/get_time/char/2.cc  -std=gnu++17 execution test

libstdc++-v3/ChangeLog:

	* testsuite/27_io/manipulators/extended/get_time/char/2.cc:
	Adjust input string so that it matches %a with or without a
	trailing period.

(cherry picked from commit 4decc1062f0f6eb44209d9d5a26a744ffa474648)
