This patch consolidates all the non cancellable fcntl calls to use
the __fcntl_nocancel identifier.  For non cancellable targets it will
be just a macro to call the default respective symbol while on Linux
will be a internal one.

Since its prototype is already defined at internal fcntl.h header, it
is removed from not-cancel.h one.

Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu.

	* login/utmp_file.c (timeout_handler): Replace fcntl_not_cancel with
	__fcntl_nocancel.
	* sysdeps/generic/not-cancel.h (fcntl_not_cancel): Remove macro.
	* sysdeps/unix/sysv/linux/not-cancel.h (fcntl_not_cancel): Likewise.
