Suricata: update to 5.0.3

Suricata: update to 5.0.3

Release notes (https://suricata-ids.org/2020/04/28/suricata-5-0-3-released/, truncated):

    This is the first release after Suricata joined the Oss-Fuzz program, leading to
    discovery of a number of (potential) security issues. We expect that in the coming
    months we’ll fix more such issues, as the fuzzers increase their coverage and we
    continue to improve the seed corpus.
