Show GPU subsystem name if possible. Fixes #1490 (#1648)

After this change, if a subsystem name exists for a GPU, we display that name instead of the device name. This should fix the issue mentioned in #1490. For example, a card that would be shown as: GPU: AMD ATI Radeon RX 470/480/570/570X/580/580X/590 before will now be shown as: GPU: AMD ATI Radeon RX 480 4GB This fallback logic is implemented in the `awk` command. Additionally, the PCI address is now stripped from the awk output because it never is desirable to print it. It is, however, still kept internally in `awk` to distinguish multiple cards of the same model.
