Such simple binary would be useful but making it perfectly portable may
cost some time.  I tried to use e.g. the busybox implementation of script
and it is broken (at least on my system) for as simple usage as we have.

So I don't know whether we should not put some lightweight test in place
in the meantime.  Possibly we could avoid 'script' usage as long as stdin
is tty 'test -t 0 || fallback_script || AT_SKIP_TEST'?  Originally was
'script' important because I mistakenly wanted to add the isatty(stdout)
check - and it is not truth anymore.  But still, for `make check 0>&-` we
should not fail.
