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

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.
