svn commit: r228166 - releng/9.0/etc/periodic/daily

Log:
  MFC r227482:
  
  The default setting, daily_accounting_compress="NO", was causing
  only 1 old file to be saved, so fix this.
  
  While I'm here, fix a very old off-by-one error causing 1 more
  file than specified in daily_accounting_save to be saved because
  acct.0 was not taken into account (pun intended). Change that, and
  use a more thorough method of finding old files to delete. Partly
  just because this is the right thing to do, but also to silently
  fix the extra log that would have been left behind forever with the
  previous method.
