SWDEV-104875 - ROCm/HSA: use the finalizer from source tree
	Right now ROCm/HSA uses finalizer from the HSA RT installed.
	This finalizer version has outdated stale SC sources.
	At the same time source tree has fresh finalizer sources matching ORCA.
	The offline tool amdhsafin is built from that sources.
	This change switches from HSA RT finalizer to the in tree finalizer.

	Testing: precheckin
	Reviewed by Laurent Morichetti and Evgeny Mankov
