interrupts: Do not refrain from parsing the irq affinities for !root

I.e. let the OS be the one to decide if access to this file is allowed
or not, and non root users can see this, at least around 4.1-rc times:

Running: procfs/procfs.py:

  31: {'affinity': [0, 1, 2, 3], 'type': 'PCI-MSI-edge', 'cpu': [178564, 0, 285828, 0], 'users': ['xhci_hcd']}
  30: {'affinity': [0, 1, 2, 3], 'type': 'PCI-MSI-edge', 'cpu': [342630, 0, 197229, 0], 'users': ['0000:00:1f.2']}
  35: {'affinity': [0, 1, 2, 3], 'type': 'PCI-MSI-edge', 'cpu': [858, 0, 565, 0], 'users': ['snd_hda_intel']}
  34: {'affinity': [0, 1, 2, 3], 'type': 'PCI-MSI-edge', 'cpu': [306, 0, 44, 0], 'users': ['thunderbolt']}

And now 'tuna -Q' works for non root users:

  [acme@zoo python-linux-procfs]$ ../tuna/tuna-cmd.py -Q
     # users            affinity
