Make cli commands yoinkable into cosmo shell

Browse source 
This lets our system() and popen() commands function sort of like
BusyBox and ToyBox. By default the Cosmopolitan Shell is lightweight.
But if you use STATIC_YOINK then you can pull the individual commands
you want into the linkage, and they'll be included in a single binary.
For example the demo binary embeds `tr` and `sed` and ends up ~140kb.
