tests: Specify a non-default root folder for regressions

The new testlib library is looking for regressions walking from
a root folder. This by default points to the tests dir.
Since all regressions are supposed to live in the tests/gem5 subdir,
the patch is assigning the gem5 subdir as a root directory.

This will prevent the example garbage to be printed in the ci framework:

Exception thrown while loading
"/tmpfs/src/git/jenkins-gem5-prod/tests/long/fs/10.linux-boot/test.py"
Ignoring all tests in this file.
