lsattr,chattr: do not open e.g. device files unless asked directly; do not follow links
Add O_NOFOLLOW (and O_NOCTTY for good measure) to open calls like e2fsprogs does.
In lsattr, when recursing, operate only on regular files, symlinks, and directories.
(Otherwise, "lsattr /dev" can e.g. open a watchdog device... not good).
At this time, looks like chattr/lsattr can't operate on symlink inodes -
ioctls do not work on open(O_PATH | O_NOFOLLOW) fds.
