[Patch v2 01/11] perf-test: propagate non-zero returns from /usr/bin/time

[david at tethera.net]

From: David Bremner <bremner at debian.org>

Unlike in the correctness tests, the most common cause of non-zero
return seems to be the user interrupting, so killing the run seems
like the friendly thing to do.
