Recommended update for permissions

This update for permissions fixes the following issues:

- New whitelisting for /usr/lib/virtualbox/VirtualBoxVM and removed
stale entries for VirtualBox(bsc#1120650)
- Ensure consistency of entries, otherwise switching between settings
becomes problematic
- Whitelist for postgresql. Currently the checker doesn't complain
because the directories aren't packaged, but that might change
and/or our checkers might improve (bsc#1123886)

This update was imported from the SUSE:SLE-15:Update update project.
