aarch64: fix 64-bit syscall argument passing
On 32bit systems long long arguments are passed in a special way
to some syscalls; this accidentally got copied to the AArch64 port.
The following interfaces were broken: fallocate, fanotify, ftruncate,
posix_fadvise, posix_fallocate, pread, pwrite, readahead,
sync_file_range, truncate.
