run-report: Use libtool wrapper to spawn the sessiond for tests

The run-report script was using the sessiond binary generated via
libtool under the ".libs/" folder. When using this binary, the consumerd
used when starting the sessiond is the one installed system-wide (if
any). This could lead to tests failures if no consumer are installed in
the system or any version mismatch occurs.

This commit fix this by using the consumerd that was built with libtool
in the local source tree.
