Fixed path of unstripped libs in CreateSymFs

Fixed path of unstripped libs in CreateSymFs

Paths of stripped libs in the device used to look like:

    /data/app-lib/*/*.so

But they now look like

    /data/app/*/.../*.so

This patch fixes this function, so that now its associated unittest
(the most time consuming one in telemetry) does not fail.
