test(generate): lock in sched_get_priority_min classification

Audit of sched_get_priority_min(2): the syscall takes a single int policy
scheduling-policy enum (not an fd or path) and returns the minimum static
priority for that policy, or -1 on error. ior classifies it as KindNull in
FamilySched, consistent with every sibling sched_* syscall and the man page.

Add TestGenerateSchedGetPriorityMinHandler (covering the identical sibling
sched_get_priority_max too) to lock in that the enter handler emits a
null_event without capturing the int policy arg, that the family is
FamilySched, and that a live exit handler emitting EXIT_RET_EVENT is
generated since this syscall returns (unlike the noreturn exit syscalls).

No classification change was required, so generated artifacts are unchanged.
