ci: Provide consistent results location in LAVA

There is an out-of-sync approach regarding the location of the results
folder: some scripts refer to it via $CI_PROJECT_DIR/results, while
others just assume it is located in the current working directory.

Usually $PWD points to $CI_PROJECT_DIR, but in some cases this is not
the case, hence let's ensure the 'results' folder can always be found
in the current working directory.
