Bug 24827: Specify UTF-8 as encoding in new_from_xml()

The MARC preview of staged records fails when a staged record contains
items with UTF-8 characters (see attached screenshots). That's because
in EmbedItemsInImportBiblio() the call to MARC::Record->new_from_xml()
does not explicitly specify 'UTF-8' as the optional encoding to use.

This patch fixes that.

Test plan (in a MARC21 instance):
0) Stage for import the test record attached to this bug report (make
   sure that 'Check for embedded item record data?' is set to 'Yes'),
   then go to Home > Tools > Manage staged MARC records and click on
   the filename you've just staged.
1) In the 'Citation' column, click on the hyperlink to launch the MARC
   preview -- notice how it fails to produce any output apart from the
   modal heading.
2) Apply the patch, and restart Plack if necessary.
3) Re-launch the MARC preview: this time the output should include the
   whole record, including the embedded item data in field 952.
4) Run the unit tests to ensure nothing was broken inadvertently:
   $ prove t
   $ prove xt
