First commit to salsa (ebumeter packaging)

[trebmuh at tuxfamily.org]

Hi all

This is my first commits on salsa so any advice is welcome. See here 
https://salsa.debian.org/multimedia-team/ebumeter/commits/master .

I did that using the web on-line interface since it is only small 
changes on debian/ files which *shouldn't* modify the actual build.

That said, because I didn't test a rebuild on a local Sid/Buster 
machine, I set d/control to UNRELEASED since I understand this will not 
trigger automatically a buildfarm-rebuild and it will wait for the 
debian/control "UNRELEASED" to be replaced by "unstable" to trigger a 
rebuild.

In my opinion, such a small update doesn't need a rebuild now, but would 
deserve a rebuild before the Buster freeze in order to reach the future 
buster-stable pool. In consequence, before the future Buster freeze, I'm 
intending to have a look at this modification to this package if nobody 
has uploaded it by then by:
- testing a pbuilder rebuild on a local sid/buster machine
- then, after checking that it rebuild and behave correctly, doing the 
move (UNRELEASED -> unstable) myself in order to trigger a rebuild for 
it to be on the next Debian "Buster" stable version

If I understand the multimedia-team packaging process correctly, I'll 
then need to add myself as "uploader" in d/control before setting it to 
"unstable".

I've got other small improvements to make to a few package (managed by 
debian-multimedia) and I would appreciate if you, knowledgeable people, 
can confirm/infirm that the way I'm doing this one is fine before I 
start doing others.
