Matthew Woehlke 99ac59d31b style: Remove trailing blank lines from all CMake sources 
Our development workflow tooling prevents trailing blank lines
from being added, but some such lines remain from before that
was enforced.  Remove them to make it easier to rename files
without triggering enforcement.
