parselogs: add a couple systemd false positives

New systemd has changed the phrasing when skipping things,
with unfortunate use of 'failed':

[    1.623667] systemd[1]: Journal Audit Socket was skipped because of a failed condition check (ConditionSecurity=audit).
[    1.688258] systemd[1]: Load Kernel Modules was skipped because all trigger condition checks failed.
