replace sched_setscheduler() with sched_setattr(). The sched_setattr() function allows setting multiple attributes at once, including the scheduling policy, priority, runtime, deadline, period, and other scheduling options. This feature provides more flexibility and control over the scheduling of processes within containers and can improve resource utilization and performance in specific use cases.

I think this makes sense as part of the runtime-specs: opencontainers/runtime-spec#1188 |

The newly introduced `src/libcrun/scheduler.c` by containers#1166 missing `#include <linux/sched.h>` for CentOS 7, which result with missing `SCHED_DEADLINE`. Moreover, for CentOS 7 build we also need to enable `-std=c99`, or upgrade build tools to gcc 11 with `. /opt/rh/devtoolset-11/enable` before build.
