functions: don't allow add_binary to re-add deps

Since we now silently overwrite instead of silently failing on existing
files and symlinks, we have a lot of sodeps which are overwritten by
various binaries -- udevd and udevadm being one example. Nip this in
add_binary by doing our own check and preventing addition of
pre-existing files in the $BUILDROOT.
