[PATCH] fs: Set the size of empty dirs to 0.

[Eric W. Biederman]

Before the make_empty_dir_inode calls were introduce into proc, sysfs,
and sysctl those directories when stated reported an i_size of 0.
make_empty_dir_inode started reporting an i_size of 2.  At least one
userspace application depended on stat returning i_size of 0.  So modify
make_empty_dir_inode to cause an i_size of 0 to be reported for these
directories.
