Drop parse from test cases that not need them

LAVA provides several ways to report result from test cases, parsing the
output is one of them, however, it is discourage since it is error prone.
For that reason Apertis provides several scripts which make use of lava-*
scripts, such as run-test-in-systemd. Unfortunately, many test cases that
use those scripts still declare parse options which are misleading.

Drop the parsing options which make use of run-test-in-systemd to avoid
confusions.
