Adolf Belka 2071b2964f graphs.pl: Fixes graph failure when the DROP_HOSTILE directory is missing ...

- If a fresh install is done then only the DROP_HOSTILE_IN & DROP_HOSTILE_OUT
   rrd directories are created.
- With the DROP_HOSTILE directory missing then when the fwhits graph is updated an error
   message is caused by the inability to open the required files.
- This patch adds an if/else loop into the fwhits graph code to deal with the two cases
   of the DROP_HOSTILE being present or not depending on the history and if a backup with
   logs has been restored from when DROP_HOSTILE was in use.
- Tested on vm testbed and created a historical line for the hostile data when it was not
   split
- There might be a simpler or better approach than this but it was the only option I
   could identify. I couldn't find anything about being able to use if loops within the
   RRD::Graph loop
