security/sudo: Update to 1.9.13p2

Major changes between sudo 1.9.13p2 and 1.9.13p1:

• Fixed the --enable-static-sudoers option, broken in sudo 1.9.13. GitHub issue #245.
• Fixed a potential double-free bug when matching a sudoers rule that contains a per-command chroot directive (CHROOT=dir). This bug was introduced in sudo 1.9.8.
