gitlab init.d script messes up PATH

Created by: samrocketman

This section of the init.d script messes with the $PATH.

If you add echo $PATH to the script you'll see the following output.

/usr/local/bin:/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
/sbin:/bin:/usr/sbin:/usr/bin

The first line is the $PATH of the current user. The second line is the $PATH of the $app_user prior to subshelling using this code.

When a user compiles ruby from source it is usually built into /usr/local/bin. This affects the latest master branch.
