configure: fix trace backend list for out-of-tree builds

Browse Source 
Since commit "c53eeaf75a04 configure: eliminate Python dependency for
--help", configure --help fails to produce the list of available trace
backends if invoked out-of-tree. It also spits the following error:

grep: scripts/tracetool/backend/*.py: No such file or directory

This patch simply adds the missing $source_path to fix it.
