Something like this:

https://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=ross/mut&id=42ec5eaf3a6c512bffe03d20e7e512e8d87343ca

Example package contents at https://pastebin.com/5FpY9xyE

If run-ptest just puts that directory at the front of $PATH then
you'll be sure to be run the busybox tool.

Bonus points for making that a function in update-alternatives.bbclass
so every recipe with this problem can use it, but that would have to
happen at do_package time because of how that class works so I'm happy
enough with this for now.
