x86: L-APIC: Set IRQ0 as edge-triggered

 IRQ0 is edge-triggered, but the "8259A Virtual Wire" through the local
APIC configuration in the 32-bit version uses the "fasteoi" handler
suitable for level-triggered APIC interrupt.  Rewrite code so that the
"edge" handler is used.  The 64-bit version uses different code and is
unaffected.
