[OE-core][PATCH 3/3] lib/oe/sbom.py: Split deduplication of CreationInfo

[Joshua Watt <jpewhacker@gmail.com>]

The deduplicate logic has a logic flaw in that it was scanning over all
deduplicated items from previous calls to find_deduplicates(). This
doesn't make any sense because the types of objects already being
deduplicated might not match the new filter. In practice, this didn't
matter because the CreationInfo comparison function doesn't do anything
that cares if the type is actually a CreationInfo; so it didn't fail
when it was passed something else.

Fix this by creating a separate instance of the deduplication object to
start with a clean state
