Consolidate non cancellable fcntl call
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.
