jobs/ttcn3: run io_uring testsuites on all nodes

After most recent patches from Pau were merged, the io_uring testsuites
run on all jenkins nodes with the ttcn3 label again!

host2-deb11build-ansible has an older host kernel and needs ulimit
memlock increased to 1 GB. I've tried out e.g. 500 MB and it isn't
enough.

Closes: OS#6405

jobs/ttcn3: io_uring: set memlock to unlimited

io_uring in the kernel memlocks a big amount of space with older
kernels, such as the kernel on host2-deb11build-ansible. It seemed to be
enough to increase it to 1 GiB. However now we see it failing again
with:

  failure during io_uring_queue_init(): Cannot allocate memory
  Aborted (core dumped)

Set it to unlimited to ensure that a low limit is not the reason we see
it failing. If it still happens after this, we probably need to make
sure that we don't run too many SUTs with io_uring in parallel on
jenkins nodes with older kernels.
