Minor compiler warning bug fix for OpenBSD systems.

Compiling psad *.c files on OpenBSD issued the following warning before this fix:

/usr/bin/gcc -Wall -O psadwatchd.c psad_funcs.c strlcpy.c strlcat.c -o psadwatchd
psad_funcs.c: In function 'send_alert_email':
psad_funcs.c:325: warning: missing sentinel in function call
