Remove linux/fanotify.h configure test.

Now we require Linux 3.2 or later kernel headers everywhere, the
configure test for <linux/fanotify.h> is obsolete; this patch removes
it.

Tested for x86_64.

	* sysdeps/unix/sysv/linux/configure.ac (linux/fanotify.h): Do not
	test for header.
	* sysdeps/unix/sysv/linux/configure: Regenerated.
	* config.h.in (HAVE_LINUX_FANOTIFY_H): Remove #undef.
	* sysdeps/unix/sysv/linux/tst-fanotify.c [!HAVE_LINUX_FANOTIFY_H]:
	Remove conditional code.
	[HAVE_LINUX_FANOTIFY_H]: Make code unconditional.
