[NTG-context] PDF/A no longer compliant?

I tried PDF/A a while back and noticed the XMP header has an extra byte
order mark which validators flagged as “??”.

I’ve attached the patch I used to remove it, however I’m still on an old
version of ConTeXt so this might not apply cleanly to yours.

You might need to open the patch in a hex editor to see the difference in
the two lines as most text editors will not show the BOM.
