package: add hashes for SourceForge-hosted packages

Since SourceForge sometimes serves us faulty tarballs, we can tons of
autobuild failures:
    http://autobuild.buildroot.org/results/9fb/9fba5bf086a4e7a29e5f7156ec43847db7aacfc4/
    http://autobuild.buildroot.org/results/6c8/6c837b244c45ac3b3a887734a371cd6d226cf216/
    ...

Fix that by adding hash files for all SourceForge-hosted packages (thos
etht did not already have it).

We normally prefer to use hashes published by upstream, but hunting them
all one by one is a tedious task, so those hashes were all locally
computed with a script that searched for SF-hosted packages, downloades
the associated tarball, computed the hash, and stored it in the
corresponding .hash file.

Also, SF publishes sha1 hashes, while I used the stronger sha256, since
sha1 is now considered to be relatively weak.
