[Build] Set all Debian package permissions to 755
[Build] Set all Debian package permissions to 755

755 means the owner can read, write, and execute, and everyone else can just read and execute. I think that's what we want here since without execute permissions others cannot open directories.

Inspired by [this comment on a separate PR](https://github.com/apache/spark/pull/3297#issuecomment-63286730).

Author: Nicholas Chammas <nicholas.chammas@gmail.com>

Closes #4277 from nchammas/patch-1 and squashes the following commits:
