chattr: improve error messages.
When chattr fails in production, it helps to see what it was trying to do. Reuse the lsattr format but without the '-'s. Only read the flags if we have any intention of changing them: `chattr -p 123` has no reason to read the flags. Only write the flags back if they actually change: `chattr +a` shouldn't do anything if that flag is already set, for example. Switch -p and -v to perror_msg() instead of perror_exit() in case they're used with -R. (I suspect that the uses of DIRTREE_ABORT are mistakes given -R, but I'll leave them until I actually hit this.)
