webdav: convert to UTC before using http.TimeFormat
http.TimeFormat hard-codes GMT and is documented that:
> TimeFormat is the time format to use when generating times in HTTP
> headers. It is like time.RFC1123 but hard-codes GMT as the time
> zone. The time being formatted must be in UTC for Format to generate
> the correct format.
These two users weren't UTC-ifying the time.Time first.
Fixes golang/go#25015
