tools/sched_ext: scx_central: fix CPU_SET and skeleton leak on early exit

Use CPU_SET_S() instead of CPU_SET() on the dynamically allocated
cpuset to avoid a potential out-of-bounds write when nr_cpu_ids
exceeds CPU_SETSIZE.

Also destroy the skeleton before returning on invalid central CPU ID
to prevent a resource leak.
