[pdftex] option to suppress the /Info dictionary

[Karl Berry]

Hi Ulrike,

    \pdfomitinfodict=1 ... But the info dictionary itself is still there

Thanks for the report, as always.

Thanh made the patch below (pdftex r885, thanks Thanh!), which I
imported into TL (r65154).  Not sure if there's any good way for you to
get an updated binary now, but should be fixed for tl23 anyway ... -k
