Move powerpc64 pread/pwrite definitions to syscalls.list (bug 14138).

Browse Source 
Concluding the move of syscall definitions to syscalls.list, where the
removal of support for old kernel versions has made this possible,
this patch removes C definitions of pread, pread64, pwrite and
pwrite64 for powerpc64.  As far as I can tell, the existing
syscalls.list definitions in
sysdeps/unix/sysv/linux/wordsize-64/syscalls.list should suffice to
produce results equivalent to what these C files do.

	[BZ #14138]
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/pread.c: Remove file.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/pread64.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/pwrite64.c: Likewise.
