BZ#16469: resolv: skip leading dot in domain to search
This should only happen if the domain to search is the root,
represented as "." rather than by an empty string.  Skipping it here
prevents libc_res_nquerydomain from duplicating the trailing dot,
which would cause the domain name compression to fail.

	[BZ #16469]
	* resolv/res_query.c (__libc_res_nsearch): Skip leading dot in
	search domain names.
