[FAB-9581] Pass sccprovider into chaincode New

Presently, system chaincodes use an antipattern of calling into another
package to ask how to do something, rather than being told how that
thing should be done.

This CR inverts the control so that at instantiation time, the system
chaincode is given the sysccprovider rather than asking for it.
