[FAB-2122] Generalize GOLANG install path

We have a defunct configuration key to specify the chaincode
install path, but it is not used.  We also specify a chaincode
specific binary name, which is not really necessary.  Therefore
we remove the defunct config item and implement a generic
binary name to clean this up.

Part of the fix for FAB-2122.
