Firecracker: Fix kernel command line parameters

Browse Source 
Firecracker does not support pci. It also uses kbd to implement reboot/reset.
Fix the kernel boot params to address this.

It also does not have good entropy at startup. Use the hardware random
number generator to support entropy.

Fixes: #1620
