lib/igt_device: Move intel_get_pci_device under igt_device
It allows us to make things a little bit more generic. Also, we now
require fd rather than doing guesswork when it comes to pci address.
v2: Use readlinkat rather than string concat, move stuff around, provide
a version that does not assert. (Chris)
v3: Print addr on failure, avoid assignment in conditionals. (Chris)
