spec: fix spec warning for /usr/include/ynl
With the combination of build options "--without realtime --without debug --without debuginfo --without ynl --without doc" in ELN, build produces a warning:
RPM build warnings: File not found: /builddir/build/BUILD/kernel-6.16.0-build/BUILDROOT/usr/include/ynl
Put the exclude behind %{with_ynl} to avoid the warning.
