bozo: Log each dir and file with bad access rights

The bosserver directory and file access check stops after finding one
directory or file with incorrect permissions or owner. A log message is
written for this first one found, but more than one directory or file
may have incorrect access rights.

Instead check all of them so the bosserver logs a warning message for
each incorrect director or file permission found.  This should make it
easier to fix all of the file permission problems at once.
