perf/x86/uncore: Fix build on UP-IOAPIC configs

Commit:

  cf6d445f ("perf/x86/uncore: Track packages, not per CPU data")

reorganized the uncore code to track packages, and introduced a dependency
on MAX_APIC_ID. This constant is not available on UP-IOAPIC builds:

  arch/x86/events/intel/uncore.c:1350:44: error: 'MAX_LOCAL_APIC' undeclared here (not in a function)

Include asm/apicdef.h explicitly to pick it up.
