[PATCH 02/11] AuthAudit: clean up string handling calls

[Alan Coopersmith]

The extra "out" pointer to redirect writes to the array isn't needed since
the removal of LBX (commit a9ed5a87902a), and eliminating it allows more
logical use of sizeof(addr) in length-checked strlcpy & snprintf calls to
write to it.
