api/v2.0/ps/ Error with <defunct> processes

[Not-Code]

Whenever the GetProcessList calls ps -e -o user,pid,ppid,stime,pcpu,pmem,rss,vsz,stat,time,comm,psr,cgroup and a defunct process is present in the returned list, the API fails and the client gets a 500 error with the following output:

process listing failed: invalid pid "24647": strconv.Atoi: parsing "<defunct>": invalid syntax

Below an example of the output that is breaking the parsing:

root 24647 10145 17:24 0.0 0.0 0 0 Z<s 00:00:00 SYNO. <defunct> 3 -

[Not-Code]

This is caused by the following line of code in container.go

psr, err := strconv.Atoi(fields[11])
if err != nil {
	return nil, fmt.Errorf("invalid pid %q: %v", fields[1], err)
}

and that part has been deleted in master:

#2751

Closing the issue and waiting for the release.

@Not-Code I will try to have the fix backported to 0.37 and 0.38.
