$(TOPDIR), make, scripts: Search-and-replace ytools -> jw-build

This project was copied from ytools, with anything not related to providing
build-functionality left out. This commit replaces the occurences of ytools
with jw-build, and removes some but most certainly not all legacy ytools
references.
