0bfd27535f nixos/libvirtd: refresh LXC emulator path on startup
This fixes the issue when the LXC emulator binary is garbage collected
and breaks libvirtd containers, because libvirtd XML file still refers
to GC'ed store path.

We already have a fix for QEMU, this commit extends the fix to cover LXC
too.

29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

0856500f3e nixos/libvirtd-service: fix fail-to-start when no machines are configured
Don't fail to start the libvirtd service just because there are no files
that match the /etc/libvirt/qemu/*.xml pattern.

f52f9bf7cd nixos/libvirtd-service: fix for garbage collected emulator paths
libvirtd puts the full path of the emulator binary in the machine config
file. But this path can unfortunately be garbage collected while still
being used by the virtual machine. Then this happens:

Error starting domain: Cannot check QEMU binary /nix/store/z5c2xzk9x0pj6x511w0w4gy9xl5wljxy-qemu-1.5.2-x86-only/bin/qemu-kvm: No such file or directory

Fix by updating the emulator path on each service startup to something
valid (re-scan $PATH).

b9f5b880e7 nixos/libvirtd-service: fix for dnsmasq (dir perms 700 -> 755)
Fixes this:

Nov 09 16:18:54 nixos-laptop systemd[1]: Starting Libvirt Virtual Machine Management Daemon...
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: read /etc/hosts - 2 addresses
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: failed to load names from /var/lib/libvirt/dnsmasq/default.addnhosts: Permission denied
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: cannot read /var/lib/libvirt/dnsmasq/default.hostsfile: Permission denied
Nov 09 16:18:55 nixos-laptop systemd[1]: Started Libvirt Virtual Machine Management Daemon.

I don't understand the reason for the original 700 permission bits.
Apparently read-access is needed and Ubuntu also use 755 perms.

Use "chmod" instead of "mkdir -m" to set permissions because mkdir doesn't
modify permissions on existing directories.

ad3a0dd8fb nixos/libvirtd: fix remote ssh managment by adding netcat-openbsd in system packages
Virsh/virt-manager uses ssh to connect to master, there it expects openbsd netcat(which
has support for unix sockets) to be avalible, to make a tunnel.

Close #1087.
