ECMAddTests: make NAME_PREFIX only apply to the test, not the target

David Faure and Patrick Spendrin have convinced me that NAME_PREFIX
should be informational only, and not be used to prevent clashes, since
it makes things confusing when you run tests manually.

This is a SIC change (although in practice only kio and kconfig should
be affected, currently).
