depthcharge: Update build

- Add prompt so the defconfig can be selected for the build.
- Remove target rename code from makefile.  The old versions don't build
with the latest vboot, so this isn't useful anymore.
- Change $(info ...) to an echo.  info prints immediately when
evaluated, which made it print when it shouldn't have, on make clean
for example.
- Split up single line shell scripts into multiple lines
- Change checkout target to only update the commit id when actually
changing versions instead of on every build.
