Subject: [PATCH] linux-dey: rt: apply sysvinit RT fragment only when sysvinit
 is enabled

The fragment-07-rt-sysvinit.config disables several cgroup
controllers (PIDS, CPUACCT, DEVICE, FREEZER, etc.) and is
intended for minimal RT configurations using sysvinit.

It is currently applied unconditionally for STM32MP RT builds,
including systemd-based systems. This breaks container runtimes
such as podman, which require full cgroup support (notably
CONFIG_CGROUP_PIDS) when running on PREEMPT_RT kernels.

Apply the sysvinit RT fragment only when the 'sysvinit'
DISTRO_FEATURE is enabled, leaving systemd configurations
unaffected.
