Consolidate non cancellable write call

This patch consolidates all the non cancellable write calls to use
the __write_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.

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

	* sysdeps/generic/not-cancel.h (write_not_cancel): Remove macro.
	(__write_nocancel): New macro.
	* sysdeps/unix/sysv/linux/not-cancel.h (__write_nocancel):
	Rewrite as a function prototype.
	(write_not_cancel): Remove macro.
	* sysdeps/unix/sysv/linux/write.c (__write_nocancel): New function.
	* gmon/gmon.c (ERR): Replace write_not_cancel with __write_nocancel.
	(write_gmon): Likewise.
	* libio/fileops.c (_IO_new_file_write): Likewise.
	* login/utmp_file.c (pututline_file): Likewise.
	(updwtmp_file): Likewise.
	* stdio-common/psiginfo.c (psiginfo): Likewise.
	* sysdeps/posix/spawni.c (__spawni_child): Likewise.
	* sysdeps/unix/sysv/linux/gethostid.c (sethostid): Likewise.
	* sysdeps/unix/sysv/linux/libc_fatal.c (backtrace_and_maps):
	Likewise.
	* sysdeps/unix/sysv/linux/pthread_setname.c (pthread_setname_np):
	Likewise.
