85efd9a80a Fix format of PDF and XMP timezone offsets
The way to specify timezone offsets differs between the PDF and XMP
specs, so hardcode the UTC offset instead of using `%z`. This also
avoids the possibility of embedding the more more granular timezones
supported by the datetime module but that are unsupported by either PDF
or XMP formats.

9c3753ed2b Convert manual creation/mod times to UTC as well
In line with the previous commit for consistency, convert the date
strings from --creationdate and --moddate to UTC as well if a timezone
is specified.

1dd05cc36b Treat default creation/mod dates as UTC (fixes #155)
(Tested with Python 3.11.3 on Arch Linux.)

Without passing a tzinfo object to `datetime.now()`, a "naive" datetime
object is created, which is not timezone-aware. To fix the default
date/time detection for non-UTC local timezones, pass
`datetime.timezone.utc` to convert the value to UTC and make the
datetime object "aware".

Also, adjust the strftime() wrappers to use the UTC offsets instead of a
literal `Z`; using the literal `Z` at the end appears to be valid for
ISO 8601, but for some reason it does not successfully convert, whereas
the `%z` placeholder substitutes the UTC offset and successfully
converts.
