Allow repository name change via git scm basename paramter

Example:
https://github.com/DMTF/Redfishtool.git
vs
network:utilities/redfishtool

In mainline project the first letter 'R' is
uppercase, but in OBS it's lowercase.

Adding basename= parameter in _service file with this patch like:
     <param name="revision">main</param>
     <param name="versionformat">@PARENT_TAG@.@[email protected]%h</param>
     <param name="changesgenerate">enable</param>
-    </service>
+    <param name="basename">redfishtool</param>
+  </service>
   <service name="set_version" mode="localonly"/>
   <service name="tar" mode="buildtime">
   </service>

results in:
redfishtool
redfishtool-1.1.7.1.gfaa99dc.obscpio
redfishtool-1.1.7.1.gfaa99dc.tar.xz
redfishtool.obsinfo

instead of (without basename param):
Redfishtool
Redfishtool-1.1.7.1.gfaa99dc.obscpio
Redfishtool-1.1.7.1.gfaa99dc.tar.xz
Redfishtool.obsinfo

With this patch it is possible to adopt or rename
any arbitrary git project name to its matching OBS project
name and process it via OBS services.
