Bug 17842: UTF-8 encode ISO2709 MARC download from cart

The cart was outputing ISO2709 MARC records with Latin-1
encoding. Records containing non-latin1 characters were
automatically re-encoded as UTF-8 by browsers, which led to
inconsistent character encodings for downloaded MARC files.

This patch explicitly encodes ISO2709 MARC characters from
the cart download as UTF-8 encoded bytes, which resolves the problem.

Test Plan:
0) Don't apply patch
1) Create bib record with only ASCII characters
2) Add a ü character to the title
3) Save bib record
4) Download bib record from cart (opac and staff client)
5) Using xxd or some other program, note that the ü is
represented by a FC byte (latin-1 encoded)
6) Apply the patch
7) Download bib record from cart (opac and staff client)
8) Using xxd or some other program, note that the ü is
represented by C3 BC bytes (utf-8 encoded)
9) Success

(Note that you could potentially use Notepad++ or some other
program to open the downloaded file and just note the encoding
that it finds. You could also try "chardetect" instead. Lots
of options for figuring out the encoding.)
