yes: fix argv test race between fork and execHEADmain

The argv test checks ps(1) output immediately after backgrounding yes(1), but
the forked child briefly shows the parent shell's argv before exec(2) replaces it.
This caused intermittent failures where ps(1) captured the atf shell wrapper
command line instead of "yes y".
