Remove version specific packages from Debian dependencies.
* debian/control (Source: mandos/Build-Depends-Indep): Remove
"python2.7", "python2.7-dbus", "python2.7-avahi", and
"python2.7-gobject"; replace with "python (= 2.7)", "python-dbus",
"python-avahi", "python-gobject".
Thanks: Scott Kitterman <debian@kitterman.com>
Closes: #811159
