The accent primitive is not an assignment (was misclassified in l3htoks)

Fix the f-expansion example in l3expan documentation

The \cs_set_eq:NN function f-expands to \tex_let:D, which is not great 
for an example of LaTeX3 code.  I've replaced it by \tl_set:Nn, which 
expands to \cs_set_nopar:Npx ... { \exp_not:n { ... } }.  Still, I 
really don't like the example's way of expanding variants into base 
functions.
