Libvirt native C API and daemons

The original logic is incorrect. We would delete the device entry from eBPF map only if the newval would be same as current val in the map. In case that the device was allowed only as read-only but later we remove all permissions for that device it would remain in the table with empty values. The old code would still deny the device but it's not working as intended. Instead we will update the value in advance. If the updated value is 0 it means that we are removing all permissions so it should be removed from the map, otherwise we will update the value in map.

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the
website:
