build:wafsamba: Ensure that target clones get a different name

Changing the 'target' attribute results in a different file name,
which is visibly necessary. Yet the 'name' attribute should also
be modified even if invisible as it is used to query targets
(uselib for example). Failing to do so results in errors in Waf 1.8.
