Update src/hardware/apic.c fix format string errors on M1 Mac

[JoeMatt]

This line caused compile issue with long with llu.

An alternative solution would be hard casting the args to (long).

APIC_LOG("  timer period %ld cur=%ld next=%ld\n", (long)apic_get_period(), (long)now, (long)apic.timer_next);
