Avoid warnings for unused results in nscd/connections.c.
This patch avoids warnings for unused results of setuid and setgid in
nscd/connections.c using an ignore_value macro along the lines
suggested by Paul in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00733.html>.

Tested for x86_64.

	* include/libc-internal.h (ignore_value): New macro.
	* nscd/connections.c (restart): Wrap calls to setuid and setgid
	with ignore_value.
