Key permissions are too open: Set correct permissions

[jantrienes]

I was trying to use the buildpack on scalingo, which also uses the same buildpack technology as Heroku. However, the application container has a different default umask than the containers on Heroku have.

Heroku:

> heroku run bash
~ $ umask   
0077

Scalingo:

> scalingo run bash
[11:19] Scalingo ~ $ umask
0022

Therefore, the permissions of the private ssh key file ~/.ssh/id_rsa are too open resulting into the following error during build:

       @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
       @         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
       @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
       Permissions 0664 for '/app/.ssh/id_rsa' are too open.
       It is required that your private key files are NOT accessible by others.
       This private key will be ignored.
       bad permissions: ignore key: /app/.ssh/id_rsa

Fix:
Change the permissions of the ~/.ssh/id_rsa file after creation to 0600.

This also affects Flynn. Could this be merged @debitoor?
