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 �.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
