Prefer Lisp version of describe-map-tree

Browse source 
This is a prerequisite to remove the old C functions, and gives a
measured 3 ms slowdown on my machine, from 0.27s to 0.30s per call to
describe-buffer-bindings (average over 50 calls).

* src/keymap.c (Fdescribe_buffer_bindings): Call Lisp function
describe-map-tree instead of C function describe_map_tree.
