x11-drivers/nvidia-drivers: move nvidia-powerd behind IUSE=powerd

Mostly due to the openrc service's "need dbus" which is an annoyance
when dbus is missing (preventing from being a runtime-only optfeature),
but even with systemd this now also allows to properly check for
multilib on dbus (used by 32bit glcore/eglcore libraries to communicate
with powerd).

*Technically* needs a revbump given --changed-use does not know it
needs to rebuild here, but given this only cause problems for rare
users without dbus (e.g. headless cuda servers with USE=-tools) and
will propagate with kernel updates+rebuilds let's not bother every
users over this.

Hopefully users of powerd (incl. for systemd which may have more
existing ones) will notice the new USE and enable it.

Also re-arrange arm64 handling, it makes more sense to mask the USE
on arm64 than keep it as a no-op by checking if use !amd64.
Exception to this is 0/550 branch which started to include a arm64
nvidia-powerd build (albeit do not think hardware that need this even
exists yet). Hope did not break installation there given did not test
on arm64, please report if so.
