libbpf: map 'processes': failed to create: Cannot allocate memory(-12)

During lockcd testing I have got following error

Oct 14 12:12:35 lockc-control-plane-0 systemd[1]: Starting lockc daemon...

How to reproduce it:

1. Build lockc project
2. Use terraform libvirt to create small VM with 2048 MB of RAM
3. Start VM and try to restart lockcd with systemctl start lockcd
4. Check lockcd status using systemctl status lockcd
