e2fsprogs builds fine with or without attr but it's possible to
end up with this sequence:
* e2fsprogs configure finds attr/xattr.h (coming from sstate)
* attr starts rebuild, attr/xattr.h is removed from sysroot
* e2fsprogs compile fails: "attr/xattr.h: No such file or directory"
Depend on attr to ensure reproducible build.
