Enable libtraceevent/libtracefs support for Fedora

[jamesjer]

As noted in https://src.fedoraproject.org/rpms/ndctl/pull-request/2, the expression 0%{?rhel} evaluates to zero on Fedora, so the conditional %if 0%{?rhel} < 9 evaluates to true, since 0 is less than 9. The result is that ndctl builds for Fedora lack support for libtraceevent and libtracefs, which is fixed by this PR.
