cleanup: make get_syscall_args.c files more readable
Make get_syscall_args.c files more self-contained. While they are
still being included by syscall.c, the latter no longer defines
get_syscall_args function.
* linux/aarch64/get_syscall_args.c: Include "arm/get_syscall_args.c"
with get_syscall_args temporarily defined to arm_get_syscall_args.
(get_syscall_args): Define.
* linux/alpha/get_syscall_args.c (get_syscall_args): Define.
* linux/arc/get_syscall_args.c: Likewise.
