Fix localealias.c fgets_unlocked namespace (bug 17589).

intl/localealias.c is brought in by ISO C functions, but uses
fgets_unlocked, which is not an ISO C function.  This patch changes
this to use __fgets_unlocked.

Tested for x86_64 (testsuite, and that stripped installed shared
libraries are unchanged by the patch).

	[BZ #17589]
	* intl/localealias.c [_LIBC] (FGETS): Use __fgets_unlocked instead
	of fgets_unlocked.
