qa/workunits/rados/test.sh: Create XML report for timeout tests

Currently the failure description in teuthology doesn't
give us much detail rather than COMMAND_FAILURE when
the test timedout, this is because when we timeout and
kill the process there are no XML files generated, therefore,
this commit will create an XML file report when we decide
to timeout and kill the long running test process.
