run-tests: explicitly handle unicode when writing xunit file

The xunit writer was passing a str to a minidom API. An implicit
.decode('ascii') was performed somewhere, causing UnicodeDecodeError
if test output contained non-ascii sequences.

This patch converts test output to utf-8 before passing it to minidom.
We use the "replace" strategy to ensure invalid utf-8 sequences get
munged into �.
