Make `run-gocd` executable by default

I tried using OSX installer it was a smooth process for me except I had to provide execute permission to run-gocd.

unzip -qq gocd-19.3.0-8674-osx.zip && cd gocd-19.3.0-8674 && ls -lrt run-gocd && cd .. && rm -rf gocd-19.3.0-8674  
-rw-r--r--@ 1 bhupendrakumar  staff  3166000 Mar 13 05:53 run-gocd

Maybe it will be better if we can bundle run-cmd with all permissions attributes. By doing this user will not have to run chmod +x run-cmd manually.

This would be nice. I know zip files aren’t great in this area. But, extended zip should allow file ownership bits to be maintained.

Or tar.gz

As long as it works out of the box in the OS and the experience is ok.
