security/sudo: Update to 1.9.8p2

Major changes between sudo 1.9.8p2 and 1.9.8p1:

• Fixed a potential out-of-bounds read with "sudo -i" when the target user's shell is bash. This is a regression introduced in sudo 1.9.8. Bug #998.
• sudo_logsrvd now only sends a log ID for first command of a session. There is no need to send the log ID for each sub-command.
• Fixed a few minor memory leaks in intercept mode.
• Fixed a problem with sudo_logsrvd in relay mode if "store_first" was enabled when handling sub-commands. A new zero-length journal file was created for each sub-command instead of simply using the existing journal file.
