Bug #22478 Agent unInstall incomplete (empty dirs 'log' and 'run' remains) (br 1515)

Description:
after unInstall (BitRock 0.6.17) the directories 

 ...\log
 ...\run

and the main directory remains on the system. 

Detected with RH4, Suse9 and Solaris8 installer.

How to repeat:
install and unInstall using the BitRock installer

Suggested fix:
remove any objects created during the install, but leave user created objects (--> remove empty directories, but leave created directories if there are objects which were not created by the installer)

FAILed with 0.7.13 on a RH4/x86 machine (net-qa1):

Reported by Bitrock as corrected in ver => 7.25

tested OK with 0.7.27 on 3 different Linux:

- empty dirs .../log and .../run were removed. 
- in one case i had in .../log an old log file, it blocked removing the dir (= OK).
- I saw only 'user created' objects remaining.
