AV1: Fixed build error on RHEL8 due to older VAAPI version. (#392)

* * rocDecode/AV1: Fixed build error on RHEL8 due to older VAAPI version.

* * rocDecode/AV1: Fixed build error on RHEL8 due to older VAAPI version.

* * rocDecode/AV1: Set VA profile for AV1 for older VAAPI versions where it is not defined.

* * rocDecode/AV1: Made rocDeocde AV1 built on VAAPI versions below 1.6.0 runnable with newer versions, to be able to test under RHEL8.
