Ooherwise, the file has wrong permissions:

  # ls -la /var/lib/NetworkManager/secret_key
  ----r-xr-x. 1 root root 50 May 14 13:52 /var/lib/NetworkManager/secret_key

Luckily, /var/lib/NetworkManager should be already

  # ls -lad /var/lib/NetworkManager
  drwx------. 2 root root 8192 May 14 13:57 /var/lib/NetworkManager

which mitigates this a bit.

Fixes: dbcb1d6d ('core: let nm_utils_secret_key_read() handle failures internally')
