Enable options required to run iwd instead of wpa_supplicant for the
aarch64 kernel config. Make it easier to test this, before we consider
switching to iwd as default (and enforcing kernel options in all devices
in main and community).
[ci:skip-build]: already built successfully in CI before disabling
CRYPTO_USER_API_ENABLE_OBSOLETE. I've built and verified the aarch64
version with this disabled locally, and I'm pretty sure that the armv7
version will build successfully too. So let's avoid the wait here.
