cmake: ensure build/latest/ is re-symlinked on every binary build

My typical workflow is to just build and run individual tests, rather
than building the entire project. This adds some cmake hackery so that
when any executable is built, it will ensure that the build/latest/
symlink is recreated, making it more likely that I can run the resulting
test using build/latest/bin/foo-test.

This also disallows running cmake from inside symlinked build/latest.
If you try to run cmake here, it ends up getting into a very confused
state, where builds fail with hard to decipher messages. It's easier
to just disallow it.
