tomoyo: use u64 for holding inode->i_ino value

TOMOYO is treating numeric fields (including inode->i_ino) as "unsigned
long". Now that commit 0b2600f ("treewide: change inode->i_ino from
unsigned long to u64") went upstream, update affected portions in TOMOYO.

While an administrator might write a rule that compares inode->i_ino with
an immediate value, this patch changes type of variable for inode->i_ino
to "u64" but does not change type of variable for the corresponding
immediate value to "u64" due to the following reasons.

  It is likely that rules that compare inode->i_ino are for testing whether
  the directories involved in e.g. rename() operation are the same (i.e.
  comparison between two inode->i_ino values rather than one inode->i_ino
  value and one immediate value).

  It unlikely makes sense to compare inode->i_ino with an immediate value
  larger than UINT_MAX.
