Subject: Improve finding the right package when searching by source name


Source name are of the type NEVR, ie: name-<epoch>-<version>-<release>,
so to avoid finding foo1 when we are looking for foo, we've adjusted the
logic to look for foo-, but this fails when there is a package such as
foo-util.
So with this commit, we ensure that the package returned is matching the
pattern <name>-<digit>.
