[PATCH v2 1/1] buildtools: clear out regex syntax warnings

[Ariel Otilibili <otilibil@eurecom.fr>]

* invalid escape sequences now generate SyntaxWarning
* therefore changed syntax to raw string noration.

Link: https://docs.python.org/3/library/re.html#module-re
Fixes: 0aeaf75df87 ("test: define unit tests suites based on test types")
Fixes: 25065ef1f6c ("test: emit warning for orphaned tests")
