Subject: [PATCH 2/4] Fix redundant argument to sprintf warning.

Perl 5.22 now warns about redundant (i.e. extra) arguments to the
sprintf function. If your format string only has two place-holders but
you pass three place-fillers, you get warned:

  Redundant argument in sprintf at ./amavis-logwatch line 1338...

The issue there was that the format string passed to sprintf was
constructed dynamically; sometimes it would contain two place-holders,
and sometimes three. Three place-fillers were always passed, so when
only two place-holders were used, the warning would be thrown. This was
fixed by testing whether or not there are two or three place-holders,
and passing the appropriate number of place-fillers.
