Convert ls(1) to not use libxo(3)

Browse source 
libxo imposes a large burden on system utilities. In the case of ls, that
burden is difficult to justify -- any language that can interact with json
output can use readdir(3) and stat(2).

Logically, this reverts r291607, r285857, r285803, r285734, r285425,
r284494, r284489, r284252, and r284198.

Kyua tests continue to pass (libxo integration was entirely untested).
