[Nut-upsdev] patch for m4/nut_check_libwrap.m4

[Tim Rice]

I ran into some issues building nut-2.4.1 on my Solaris 10 machine.
Here is a patch for m4/nut_check_libwrap.m4 to fix libwrap support.

-----------------------
#	m4/nut_check_libwrap.m4
#	test needs to use TRY_LINK
#	Undefined                      first referenced
#	 symbol                            in file
#	deny_severity                       /usr/sfw/lib/libwrap.so
#	allow_severity                      /usr/sfw/lib/libwrap.so
#   	Run yp_get_default_domain first or it will choke with the above
#	error too because of -lwrap
