CPP generate-bazel-project-template is failing during build, due to extra space … in the BUILD.bazel file. This commit fixes that.
Before fix:
```
$ ray cpp --generate-bazel-project-template-to ray-template
Project template generated to /home/soumitra/opensource/ray-template
To build and run this template, run
cd /home/soumitra/opensource/ray-template && bash run.sh
$ cd ray-template/
$ bash run.sh
Starting local Bazel server and connecting to it...

The problem is seen in ./bazel-bin/example-2.params file:
$ cat ./bazel-bin/example-2.params

```
After fix:
```
