tests/int/cgroups.bats: exclude dmem controller

The dmem controller is added into kernel v6.13 and is now enabled in
Fedora 42 kernels. Yet, systemd is not aware of dmem.

This fixes the test case failure on Fedora.

For the initial test case, see commit 2751571.

For earlier commits similar to this one, see
commits 601cf58, 0527271, e83ca51.
