posix: Consolidate Linux nanosleep syscall
This patch consolidates the nanosleep Linux syscall generation on
sysdeps/unix/sysv/linux/nanosleep.c.  It basically removes it from
architectures auto-generation list.

Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu,
sparc64-linux-gnu, and sparcv9-linux-gnu.

	* nptl/Makefile (CFLAGS-nanosleep.c): New rule.
	* posix/Makefile (CFLAGS-nanosleep.c): Likewise.
	* sysdeps/unix/sysv/linux/nanosleep.c: New file.
	* sysdeps/unix/sysv/linux/syscalls.list: Remove nanosleep from
	auto-generated list.
