arm: fixed AArch64 syscall numbers

It turned out that AArch64 uses the UAPI syscall numbering scheme
that is incompatible with x86. Unfortunately this kills the idea
of the unified syscall table and syscall generator.

Note that the following syscalls:

* open,
* mkdir,
* rmdir,
* unlink,

are declared obsolete in the UAPI. Moreover the syscall arch_prctl
doesn't exist in the UAPI.
