build(kernel-hwe): disable CONFIG_AF_RXRPC on aarch64

Align aarch64 with x86_64 by disabling AF_RXRPC. AFS_FS (the only
in-tree consumer of RXRPC) is already disabled in the kernel-hwe
configs, so AF_RXRPC has no user. Drop the now-unreachable child
symbols (AF_RXRPC_IPV6, AF_RXRPC_INJECT_LOSS, AF_RXRPC_INJECT_RX_DELAY,
AF_RXRPC_DEBUG, RXKAD, RXPERF) so 'make oldconfig' converges and the
build's config-drift check passes.
