losetup: try to set up loop readonly if EACCES
Currently mounting/losetup an image fails if it is accessable readonly.
There are no problems if it is a file on a local filesystem.
It seems only to happen if it is a NFS mounted image, which is
read-write in permission but with root_squash option.
set_loop checks only for EROFS to retry open with readonly mode,
but in this case we get EACCES.
