[509216] Use icons located in org.eclipse.mat.ui.rcp for the RCPs

The icons for the product were present redundantly - in
org.eclipse.mat.ui.rcp and in org.eclipse.mat.product. This change
deletes one of the copy and leaves the ones within the rcp plugin.
This plugin also contains the branding information.
