[LTP] [PATCH] controllers/cpuacct.sh: Fix timeout for cpuacct.sh

[Petr Vorel]

Hi Xiao,

> With commit fbea02a, cpuacct.sh always gets timeout because wait
> command tries to wait all background processes including the timeout
> process.  We should just wait the processes created for test.

> cpuacct 1 TINFO: timeout per run is 0h 5m 0s
> cpuacct 1 TINFO: cpuacct:
> cpuacct 1 TINFO: Creating 1 subgroups each with 1 processes
> cpuacct 1 TBROK: test killed, timeout!
> -----------------------------------------------------------

Thanks for your fix, merged.

I look for other plain wait usage, this was the only one using new shell API.

Kind regards,
