[Xen-devel] [OSSTEST PATCH 3/4] cs-bisection-step: Print our command line at the start

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

The usual approach for debugging the cs-bisection-step is to repro the
problem (with --max-flight), which is most easily done by copying the
command line provided during a run which did the wrong thing.

Print the command line at startup, so that it appears in the report.
This will save us grobbling through the logs and cron mail.
