[enroot] `expose_enroot_logs` breaks `--pty` argument in `srun`

[itechdima]

the process is stuck

srun -G8 --container-image=ghcr.io#coreweave/nccl-tests:12.4.1-cudnn-devel-ubuntu22.04-nccl2.23.4-1-2ff05b2 --pty bash
cpu-bind=MASK - worker-0, task  0  0 [1880283]: mask 0xffffffffffffffffffffffffffffffff set

if we disable expose_enroot_logs, then it works fine:

srun -G8 --container-image=ghcr.io#coreweave/nccl-tests:12.4.1-cudnn-devel-ubuntu22.04-nccl2.23.4-1-2ff05b2 --pty bash

Plus, don't print lines about file locking

we've migrated to the native pyxis with importer caching mechanism, not relevant anymore
