LU-5418 libcfs: only define noop_*_fn when readline is used

This fixes a compilation break introduced by change 7629b7.
When readline devel is not found on the system,
the code using readline is not used, including
noop_int_fn() and noop_void_fn().
This generates a couple warning about these
function being unused, which breaks the build.
