tests: suppress "unwanted log lines" in several fuzzers

According to https://oss-fuzz.com/fuzzer-stats/by-fuzzer/fuzzer/libFuzzer/job/libfuzzer_asan_systemd,
fuzz-network-parser, fuzz-netdev-parser and fuzz-journal-remote produce
a lot of unwanted log lines. Let's set the maximum log level to LOG_CRIT
as we do in the other fuzzers.
