[PATCH v2] CU185-update.sh: Add drop hostile in & out logging entries if not already present

[Adolf Belka <adolf.belka@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 2201 bytes --]

- This v2 patch corrects that the previous script was looking for =on. If a user had
   modified the preferences to change it to =off then the script would have resulted in
   both =on and =off versions being in the settings file.
- This patch ensures that those people who updated to CU184 before the CU184-update.sh
   patch fix to add the logging entries was added will get their optionsfw settings file
   correctly updated with CU185
- This only adds the LOGDROPHOSTILEIN & LOGDROPHOSTILEOUT entries if they do not already
   exist in the optionsfw settings file.
- This change also does the check for LOGDROPHOSTILEIN and LOGDROPHOSTILEOUT as two
   separate checks and then runs the firewall update command
