As part of QA runs stumbled upon this case

When building and running docker tests (using GtiLab and/or manual run with a SQARDs combo - https://github.com/pevma/sqard) "older" OS dockers - for example Xenial/Stretch compile and run suricata tetss normally and as expected.
"Newer" OSs - like Debian Testing/Fedora latest get stuck on any suricata command (example "suricata -T" would get stuck on getrandom() and never complete) see below -

A quick way to test it and reproduce -
docker pull pevma/sqard:debian-testing && docker run --security-opt="apparmor=unconfined" --cap-add=SYS_PTRACE --name sqard-debian-testing-01 -d -ti pevma/sqard:debian-testing /bin/bash && docker attach $(docker ps -a |grep sqard-debian-testing-01 | awk '{print $1}')
Once inside -
git clone https://github.com/OISF/suricata.git && cd suricata && git clone https://github.com/OISF/libhtp.git -b 0.5.x && ./autogen.sh && ./configure --enable-hiredis --enable-rust --enable-unittests --enable-debug CFLAGS="-ggdb3 -O0" && make clean && make -j4 && make install-full && ldconfig

Guess it would be good to test for:
getrandom(0x76911f876770, 8, 0) = -1 ENOSYS (Function not implemented)
and fall back to an older method.
