[gnome-disk-utility/udisks2-port] Add a "read-only" check-button when attaching disk image and default to TRUE

[David Zeuthen <davidz src gnome org>]

commit a841fc1c9fa64d7deef1097032ae494c61a7917e

    Add a "read-only" check-button when attaching disk image and default to TRUE
    
    Otherwise it's way too easy to accidentially overwrite the contents of
    the backing file, e.g. an ISO image or similar.
