agent(rhel8): skip a part of test-fs-util

Since it's broken with newer kernels (which we have to use due to lack
of CentOS 8 / CentOS Stream 8).

+# FIXME (also not really): test-fs-util with newer kernel
+# This test fails with newer kernels, because we're missing a couple of patches in RHEL 8. Since there's no
+# CentOS 8 (nor CentOS Stream 8), we run the tests on C9S and hit this issue. It's very unlikely we'll backport
+# the necessary patches to RHEL 8, so drop the failing test for now.
