Consolidate remaning non cancellable definitions
This patch consolidate the remaning non cancellable syscall definitions
on not-cancel.h header. They are:
* __fcntl_nocancel: Moved from fcntl.h to not-cancel.h.
* __sigsuspend_nocancel: Removed since 988f991b50 it is not used or
defined anymore.
* __nanosleep_nocancel: Removed since 6f33fd046b it is defined on
not-cancel.h.
Now all non-cancellable syscall definition are defined on not-cancel
(the only exceptions is the stdio symbol __fxprintf_nocancel which
uses non cancellable open and it is used on getopt implementation).
Checked on x86_64-linux-gnu and with build-many-glibc.py.
* include/fcntl.h (__fcntl_nocancel): Remove definition.
* include/signal.h (__sigsuspend_nocancel): Likewise.
* include/time.h (__nanosleep_nocancel): Likewise.
* sysdeps/generic/not-cancel.h (__fcntl_nocancel): New macro.
* login/utmp_file.c: Include non cancellable syscall header.
* sysdeps/unix/sysv/linux/not-cancel.h (__fcntl_nocancel): New
prototype.
