Sync apt-cacher-ng 0.4.9-2 (universe) from Debian unstable (main)

Please sync apt-cacher-ng 0.4.9-2 (universe) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
> * update-manager -d requires access to the DevelReleaseAnnouncement
> accessing it with a ?lang=foo suffix. Add this to the persistant
> files list. LP: #601883.
I forwarded this patch to Debian and it has been fixed in 0.4.9-2.

> * Fix no matching function for call to stat::stat(const char*,
> stat*) error and hence FTBFS LP: #596452
Fixed in 0.4.8-1.

Additionally the Ubuntu package has been converted to source format 3.0
but that's not a good reason to diverge from Debian.
