[PATCH] report: encode XML Character Entities in xUnit report

["Theodore Ts'o" <tytso@mit.edu>]

Since the xUnit report is an XML document, special XML characters such
as '<', '>', '&', etc. have to be encoded as "&lt;", "&gt;", etc.
Otherwise programs parsing something like this:

	<testcase classname="xfstests.global" name="generic/450" time="0">
		<skipped message="Only test on sector size < half of block size" />
	</testcase>

Will get choke the unescaped '<' character in the skipped message.
