FAB-950 self-contained chaincode deploy test setup

Tests that need to deploy chaincode need the following setup:
- GOPATH environment variable
- chaincode available at the folder corresponding to
$GOPATH/src/<the GO package>

have this be part of the test fixture so contributors don't have to
manually set it up locally. set process.env.GOPATH in the code to
the test fixture folder just for the test execution.
