configure.in: only add -lnsl when needed
dpkg-shlibdeps: warning: dependency on libnsl.so.1 [..] (they use none of its symbols). As shown via commit 2b14234abc252383679bae2d23861b773dc9713e (dpkg-shlibdeps: warning: dependency on libnsl.so.1) and the following revert of that commit, we cannot simply drop the AC_CHECK_LIB(nsl). Although -lnsl is indeed unneeded when glibc is used, some platforms (e.g. Solaris) need it. Use AC_SEARCH_LIBS instead to only link when the library exports a particular symbol.
