I think it might be OK to stop generating this file, but I'm worried that new
commits on previously cut release branches might depend on the LASTCHANGE.blink
file. Doesn't seem to hurt to leave this in here, and I can remove it later.

I vaguley remember the build/util/lastchange.py didn't work for us. Probably,
because of the partial checkout? Now that we have full checkout it should be ok,
right?
