lib/config: Add file inside folder marker directory (#9525)
### Purpose

Avoid the issue where the folder marker is deleted by overzealous
cleanup tools because it's just a useless, empty directory.

We create a small file containing a an admonishment to not delete the
directory, and some metadata that is just for human consumption at the
moment. (But it would parse as a valid yaml file if we wanted to read
this, at some point.)

This will only apply when _creating_ a folder marker, that is, existing
setups will not gain the file automatically. Obviously, when using a
custom folder marker none of this applies.

Also, slightly adjust the permission bits for the folder marker directory and file on Unixes, making sure the group & write bits are unset.

### Testing

I've created and deleted a few folders and it appears to behave as I
expect.
