debian/control: remove build-dep on libnotify-dev

Mozilla isn't using the notify mechanismus of new messages etc. via
message notify daemon since several versions so we don't ned this build
depenency anymore.
Note: Ubuntu is using the old message notify function because they
maintain a patch to provide this functionality. In Debian we are unably
to do this too do a lack of free time to maintain such a patch too on
top of the current patchqueue.
debian/control: increase b-d on libnss3-dev to 3.16.2~

The source need at least version 3.16.2 of the libnss3 development
files.
