Bugzilla Bug 220171

When /var/db/pkg or the portage tree lie on their own logical volumes or
partitions and a lost+found-directory is created, emerge and gentoolkit's
utilities (tested with glsa-check and equery) try to access that directory.
This makes it impossible to use these tools with an ordinary member of the
portage-group because he/she doesn't has the right to access lost+found.

Reproducible: Always

Steps to Reproduce:
To trigger it with emerge:
1. Put your portage tree on a separate ext2-filesystem and run e2fsck -f on it;
or `mkdir /usr/portage/lost+found && chown root:root /usr/portage/lost+found &&
chmod 700 /usr/portage/lost+found`
2. `emerge -pv portage` as a user in the portage-group

Actual Results:  
These are the packages that would be merged, in order:

Calculating dependencies \Permission denied: '/srv/portage/lost+found'

Expected Results:  
These are the packages that would be merged, in order:

Calculating dependencies... done!
