linux-user: Fix up AArch64 syscall handlers

Browse Source 
Some syscall handlers have special code for ARM enabled that we don't
need on AArch64. Exclude AArch64 in those cases. In other places we
can share struct definitions with other targets or have to provide our
own.

With this patch applied, most syscall definitions in linux-user should
be sound for AArch64.
