Arch Linux

Description:

When running check_procs, etime is blank. For example:
```
$ check_procs --metric=ELAPSED -w 120 -c 240 -vv
CMD: /usr/bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm args'
Matched: uid=0 vsz=38752 rss=9524 pid=1 ppid=0 pcpu=0.00 stat=Ss etime= prog=systemd args=/sbin/init
...
```
You can see that etime is not reported, and hence I cannot filter with `--metric=ELAPSED`.

I found this Fedora bug report from 12 years ago and tried appending to `./configure` as per the comment [a]:

```

etime now works perfectly

```
$ check_procs --metric=ELAPSED -w 120 -c 240 -vv
CMD: /usr/bin/ps -eo 's uid pid ppid vsz rss pcpu etime comm args'
Matched: uid=0 vsz=38752 rss=9528 pid=1 ppid=0 pcpu=0.00 stat=S etime=12:54:36 prog=systemd args=/sbin/init
```
