Based on the above, one can see that the socket program was built, but its parent directory was not present. If one inspects the corresponding Makefile, usr/src/test/zfs-tests/tests/functional/cli_root/zfs_diff, then you'll find that there's a missing dependency between the output program in the proto area and its parent directory. While the included Makefile.com has dependencies for the shell scripts that it picks up, it doesn't have any such dependency for programs. The solution is to add an explicit dependency for this case.
