Since 367b315 (perf timechart: Add support for -P and -T in timechart
recording, 2013-11-01), the 'perf timechart record' command stopped
working:

  $ perf timechart record -- git status
  Workload failed: No such file or directory

This happens because of an off-by-one error while preparing the argv for
cmd_record(): it attempts to execute the command 'status' and complains
that it doesn't exist. Fix this error.
