While testing around with php8, I stumbled across https://github.com/matomo-org/matomo/pull/15472/commits/79603337e81a1a7cfe889c34fdb4e9cb740d253f which is a test that tries to force a
PHP Fatal error: Allowed memory size of X bytes exhausted on php-cli.
Unfortunately, on my system (and probably others too) php-cli has a memory_limit of
-1 which means the PC will run out of memory before one can notice what command is running.
This PR adds a slight hack to skip this test in this case.
