ArakoonInstaller should not chown and chmod its logsinks directories recursively

[kvanhijf]

ArakoonInstaller does a recursive chown ovs:ovs and chmod 0755 for all of its directories:

• tlog dir
• home dir
• log sinks
• crash log sinks

The latter 2 will cause much side effects in case a user decides to switch to 'file' logging instead of the default 'console:' This is because in this case the log sink directories are /var/log/ovs, which contains all of our logfiles
