[libcxx] [test] Fix the locale get_one_wide test for windows and glibc

[mstorsjo]

Retry the CI, rebased to an older version where there hopefully aren't any other unrelated CI failures.

SGTM but I'd like to understand why tm_wday can't be tested on Windows.

libcxx/test/std/localization/locale.categories/category.time/locale.time.get.byname/get_one_wide.pass.cpp

68

Does Windows lack this tm member? If so please add a comment.

Those tests try to parse a date string in a format that corresponds to what strftime("%c") produces. On Windows, the %c time format lacks the leading week day, which means that we must omit it from the input text string in the test, and after parsing it, tm_wday isn't filled in as it wasn't part of the string. I guess I should add a comment that explains this.

[mstorsjo]

Added a comment to clarify the missing week day in the string and the ifdeffed out check for the tm_wday member.

LGTM!
