x86: Control interrupts in vendor-specific way

Jailhouse runs with GIF cleared on AMD, and simple 'sti' and 'cli'
aren't enough to enable and disable interrupts. This affects apic_clear()
which fails to reset IRR on AMD. To overcome this, former enable_irq()
and disable_irq() are now defined in svm.c/vmx.c in vendor-specific way.
