[attrs] look at capture DB only -- uninit.ml

Summary:
`AnalysisCallbacks.proc_resolve_attributes` introduces non-determinism because it first looks for the attributes in a (procdesc in a) summary and if it doesn't find it then returns the value in the attribute column from the capture DB.

The problem is:
- the main factor affecting the existence of a summary on-disk is timing;
- the two proc descs are generally different, as the one in the summary is preanalysed and the one in the capture DB is not;
- this extends to the attributes included in the proc desc in some cases.

The plan is to eliminate these calls one by one, replacing with `Attributes.load` which only looks at the capture DB attribute column.
