check_procs: improve ps args autodetection

one of the first ps commands in the configure.ac is `axwo 'stat comm vsz rss user uid pid ppid args'` which
works on most modern linux systems (checked debian 10/11 and centos 7/8). But this test misses the etime
argument. Therefore `check_procs --metric=ELAPSED` does not work.

To fix this, we simply do the same test including etime before that one.

 dnl so test for this first...
