Fix linux-doc, linux-manual, linux-source, linux-support package names

We don't want to include "-4.9" in them twice.  Add a "source_basename"
template variable that excludes any version suffix in the source package
name.

(cherry picked from commit f3c51efdd6e9d0ce32ee5a0f998fdcda930a715c)

For master, nothing is immediately broken without this.  Also we have
no longer build a linux-manual package.  Change the changelog text
accordingly.
