tests/int/cgroups.bats: exclude dmem controller

The dmem controller is added into kernel v6.13 and is now enabled in
Fedora 42 kernels.

This fixes the test case failure on Fedora, which got a new kernel and a
new cgroups controller (dmem) not (yet) supported by systemd.

For the initial test case, see commit 2751571.

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