Add new v1.14 Firecracker version (#15)

v1_14: add new version

Firecracker team disclosed a vulnerability on the VirtIO PCI
implementation [1]. We are not affected since we don't use PCI for our
sandboxes, but we might want to enable that in the future, so we rebase
our changes on top of the fixes. This commit creates a new build that
uses the fixed version.
