Create home directory in docker images

The recent change to use `useradd -M` in baseos and ccenv
Docker images caused building of Go chaincodes to fail with error:

"failed to initialize build cache at /home/chaincode/.cache/go-build: mkdir /home/chaincode: permission denied"

Changing it back to allow creation of the chaincode home directory
with `useradd -m` solves the problem.
