Subject: [PATCH] Modify test ```TestGbBuildSubPackageOfCmd``` to show that
 ```gb generate``` on subdirs of ```cmd```.

Problem:
    For subdirectories of ```src/cmd```, running ```gb generate``` fails to
    import:

    ```
    --- FAIL: TestGbBuildSubPackageOfCmd (0.06s)
        gb_test.go:179: running /tmp/testgb347664536/testgb [generate]
        gb_test.go:193: standard error:
        gb_test.go:194: can't load package: package cmd/hello: open /usr/lib/go/src/cmd/hello: no such file or directory
            FATAL: command "generate" failed: exit status 1

        gb_test.go:203: gb [generate] failed unexpectedly: exit status 1
    ```

    It appears that the ```gb generate``` import path only includes
    $GB_GOROOT.

Proposed solution:
    Add $GB_PROJECT_DIR to the import search path for ```gb generate```.
