Bug 2059397

To reproduce this you need to install "kernel-rt-debug" and
run libguestfs-test-tool.

Removing TestOnly because:

***   This is unapproved because at least one of the BZs contains the TestOnly keyword. TestOnly keyword must be removed in order to pass approval.

Test with supermin-5.2.1-8.el9.x86_64:

Steps:

1. On rhel9.1 host
# rpm -q kernel kernel-rt kernel-rt-debug
kernel-5.14.0-72.el9.x86_64
kernel-rt-5.14.0-72.rt21.72.el9.x86_64
kernel-rt-debug-5.14.0-72.rt21.72.el9.x86_64

2.
