David Hildenbrand 6da4b1c25d softmmu/physmem: Hint that "readonly=on,rom=off" exists when opening file R/W for private mapping fails 
It's easy to miss that memory-backend-file with "share=off" (default)
will always try opening the file R/W as default, and fail if we don't
have write permissions to the file.

In that case, the user has to explicit specify "readonly=on,rom=off" to
get usable RAM, for example, for VM templating.

Let's hint that '-object memory-backend-file,readonly=on,rom=off,...'
exists to consume R/O files in a private mapping to create writable RAM,
but only if we have permissions to open the file read-only.
