Fix pl/perl test case so it will still work under Perl 5.36.
Perl 5.36 has reclassified the warning condition that this test case used, so that the expected error fails to appear. Tweak the test so it instead exercises a case that's handled the same way in all Perl versions of interest. This appears to meet our standards for back-patching into out-of-support branches: it changes no user-visible behavior but enables testing of old branches with newer tools. Hence, back-patch as far as 9.2. Dagfinn Ilmari Mannsåker, per report from Jitka Plesníková. Discussion: https://postgr.es/m/564579.1654093326@sss.pgh.pa.us
