Title: Update PATH instead of overriding it

The builds on my continuous integration server are failing because they rely on the `PATH` being set appropriately, and `xctool` overrides it.

I changed the code to instead append the `/usr/bin`, `/bin`, `/usr/sbin`, and `/sbin` to the `PATH` instead of overriding it entirely, and now everything works.
