tests: be really robust to Perl missing

Browse Source 
My previous tests (with ./configure PERL=false) have been fooled by
configure, that managed to find perl anyway.  This time, I ran this on
a Fedora in Docker, without Perl.

* tests/calc.at, tests/diagnostics.at, tests/headers.at,
* tests/input.at, tests/local.at, tests/named-refs.at,
* tests/output.at, tests/regression.at, tests/skeletons.at,
* tests/synclines.at, tests/torture.at: Don't require Perl.
