fuel-plugin-ovs: Simplify debian version strings

Remove all suffixes from OVS debian packages, and simplify the
plugin code handling the fetching of said packages.

While at it, enable:
- local mirror caches, by mounting /etc/hosts in the docker
  builder
- HACK: mismatch between debian source versions and debian binaries

+Subject: [PATCH] HACK: build: prebuilt DEBs: src/bin ver mismatch
+
+Our debian source version is not always in sync with the debian
+binaries versions, see related bug for a complete description of
+this issue.
+
+This is a temporary chance which should be dropped once the package
+versions are aligned.
