Wrap package maintainer names in double-quotes

I am getting error messages like this:

    Now running lintian...
    E: ros-groovy-libfreenect changes: changed-by-address-malformed Jack O'Quin <jack.oquin@gmail.com>, Piyush Khandelwal <piyushk@gmail.com>

This does not appear to break anything essential. The release still succeeds.

Tully recommended also making sure that Debian control files do allow multiple maintainers.
