Fix udev rules styling

[jmalmari]

Before:

$ udevadm verify Support/60-orbcode.rules
Support/60-orbcode.rules:8 style: a comma between tokens is expected.
Support/60-orbcode.rules:10 style: a comma between tokens is expected.
Support/60-orbcode.rules: udev rules have style issues.

1 udev rules files have been checked.
  Success: 0
  Fail:    1

After:

$ udevadm verify Support/60-orbcode.rules

1 udev rules files have been checked.
  Success: 1
  Fail:    0
