build: Use -f when copying sources
If one of the source files we copy is non-writeable, cp will create a
non-writeable copy. If the original is later modified, cp will fail to
overwrite the copy since it is not writeable. Using cp -f ensures the
copy always succeeds, as long as the object directory is writeable.
