[PATCH] testprogs:subunit.sh: Add function for expected failures.

[Andrew Kroeger]

The testit_expect_failure() function is like the testit() function, with
reversed error detection logic.  This reversal only affects the pass/fail logic
and logging - the original return code from the command is still returned to the
calling script.
