More performance improvements
Instead of using `x := $(x) foo`, make sure `x` is initialized first,
then use `x += foo`.
For a aosp-master/aosp_crosshatch-userdebug build, this takes the build
from 49s to 33s (no significant difference in peak memory)
Bug: 158488548
Test: build-aosp_crosshatch.ninja is the same before/after
