Subject: tcp-wrappers: drop libnsl2 build dependency

The only libnsl2 function which is used by tcp-wrappers is
'yp_get_default_domain()'.  When USE_GETDOMAIN is set, this is
implemented as a simple wrapper around getdomainname() so that libnsl2
is not used at all.

We added a patch which does '#include <rpcsvc/ypclnt.h>' to avoid
implicit forward declaration.  By conditionalizing this, the libnsl2
dependency can be dropped completely.

(From OE-Core rev: b013f6ce40d315c894064cf9fa77d9c7a9dad2b0)
