Revert "Install static element files"

Needs more thought about how to ensure files are owned by the correct user. The only way which occurs to me is a manifest file and I'm not sure that fits within the "convenience budget" compared to installing files with install.d scripts.

This reverts commit 00b7e98af1e8b7f14895736e4df079757624948e.
