Subject: [PATCH] convert/convert_windows.ml: Handle date formats with dots
 instead of /

If the ShortDatePattern is yy.M.d (as can happen for US locale) we may
not always reformat the date for schtasks.exe correctly.  For
explanation and testing see:

https://bugzilla.redhat.com/show_bug.cgi?id=1895323#c46 (- #c50)

Thanks: Xiaodai Wang for suggesting the fix and testing it

(cherry picked from commit d9dc6c42ae64ba92993dbd9477f003ba73fcfa2f)
