Summary: core dunmp for many plugins under Solaris

Initial Comment:
On Solaris, many of the plugins core dump when 
provided with an invalid option:

./check_http -X
./check_http: invalid option -- X
Segmentation Fault (core dumped)

But not all:

./check_disk -Z
./check_disk: invalid option -- Z
Unknown argument
Usage: check_disk -w limit -c limit [-p path | -x 
device] [-t timeout][-m] [-e] [-W limit] [-K limit] [-
v] [-q]

plugins/utils.c is trying to printf a null char 
pointer.  Although many UNIXes catch this and print 
<NULL> or <null>, Solaris core dumps with SIGSEGV.

Thus I propose this following patch:

Oops, obviously I reversed that and meant:
