The xunit-quiet format exludes the NNN.{full,dmesg,bad} files in
<system-out> and <system-err> nodes.

For test runners that save the entire results directory to preserve
all of the test artifacts, capturing the NNN.{full,dmesg,bad} in the
results.xml file is redundant.  In addition, if the NNN.bad is too
large, it can cause the junitparser python library to refuse to parse
the XML file to prevent potential denial of service attacks[1].  A
simple way to avoid this problem is to simply to omit the <system-out>
and <system-err> nodes in the results.xml file.
