minor ltdl.c fix


From: Michael Pruett
Subject: minor ltdl.c fix
Date: Tue, 4 Sep 2001 19:11:00 -0700
User-agent: Mutt/1.2.5i

Currently tryall_dlopen_module is called with 0 as the argument for the
parameter prefix, of type const char *.  Doing so without a cast
results in warnings.  I believe NULL should be passed instead.
