tests/util/grub-fs-tester: Use CSMACINTOSH encoding instead of macroman

From Debian 12 to 13, recode had a major overhaul and now does not support
the macroman encoding. Its unclear if this is a bug or intentional.
Regardless, use the CSMACINTOSH encoding instead as MacRoman and it are
aliases and CSMACINTOSH is supported on both Debian 12 and 13.
