[BUG] custom config is not rendered with "netlab initial -o" if it is located on a subdirectory

[ssasso]

In https://github.com/ipspace/netlab/blob/fb1bd7928e410e2d9dd071996b5a487d1c969da7/netsim/ansible/tasks/create-custom-config.yml#L21

if the custom config is on a subdirectory, the template actions fails.

Topology example:

provider: clab

defaults.device: vyos

nodes:
  igw01:
    config: [ "extra/igw01.j2" ]

links:
- igw01:

Significative output (with ansible -vvv)
