fix db_tree_dump_wrapper for unit test usage

[mmusich]

PR description:

I casually noticed in the cmssw dashboard that CondTools/SiStrip is silently failing because the db_tree_dump_wrapper.py script cannot find locally the cmsRun executable configuration, see log
This PR fixes the issue and also changes the execme method in order to raise a python error instead of silently failing.

---> test SiStripDAQ_O2O_test had ERRORS

Failure is unrelated. That test is also randomly failing in IBs (see log)

This pull request is fully signed and it will be integrated in one of the next master IBs (but tests are reportedly failing). This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
