feat(pci): enable PCI for guests

Add kernel configuration for enabling PCI support in microVMs.
Configuration is taken from here:
https://github.com/firecracker-microvm/firecracker/blob/firecracker-v1.14/resources/guest_configs/pcie.config

Also, release this as a new (patch) kernel version so that we make
deployment cleaner.
