[PATCH] cramfs is ro only, so honour this in inode->mode

Hi Linus,
hi all,

cramfs is a read-only fs. So we should honour that in inode->mode
to avoid confusion of programs.

My isofs shows this too, so I think I'm right deleting the write
permissions in the inode. May be we should change it in
mkcramfs (too).

I don't know what POSIX says about RO fs, but I can't find any
real sense in having W permissions for an RO fs.

The patch:
