Comment 4 for bug 1933090

I run the test locally on a vm running linux-oracle-5.15-1029.
It seems `syscall(__NR__sysctl, NULL)` returns ENOSYS(38) -- Function not implemented.
Checking `/proc/kallsyms` it seems sysctl is not implemented indeed.

If I take a closer look at jammy-ubuntu tag in systemd source (test that is not failing currently)
I can see that it asserts for either EFAULT or ENOSYS:

assert_se(IN_SET(errno, EFAULT, ENOSYS));

This patch will solve the issue:
