On most systems the only process with a SID=1 is init
and certainly not a test sleep. On docker systems this
test program IS on SID=1 and so our "impossible SID" becomes
possible.
The ps sched test has been disabled. There are too many
odd build farms this fails in strange ways.
Other odd build farms have no tty and so some tests check
for no tty and skip if not found.
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.
Some Debian pbuilders error out on some of the tests because
they cannot find kill to kill the test processes. Now if we
cannot find kill we skip those lot of tests.
Still need to work out why the S390 doesn't like test_sched

When ps is not available (like it may happen in a chroot), pgrep.exp and pkill.exp tests fail.
Use just build ps instead.
