Add BG botnet check, update rpm check, add apache listening port info

Add BG botnet check:
  In addition to the files we've seen ourselves, got a full list of files to check from rkhunter, minus the tmp files.
  Also re-ordered the location of the umbreon and jynx2 checks to group them with the other malware checks.

Update rpm check:
  Added a 'apache-tomcat-apis' to the exclusion regex so we don't trigger on it any more.

Apache listening port info:
  Prints a list of ports that Apache is currently listening to (if found).
