Reliably kill test processes

It seems command -v also includes built-ins so checking for kill
is useless because it finds the built-in and those machines or
environments that have no /bin/kill fail at the check stage.
Oh and then TCL exec doesn't spawn a shell.

After reading way too many TCL websites, I believe this should
fix the problem. TCL quoting is... different to say the least but
it works reliably here. The script now even picked up a typo elsewhere
which was nice.

This change should stop the intermittent FTBFS bugs from the Debian
pbuilders, I hope! You'd think kill $var wouldn't be this difficult.
