nativesdk: don't unset MACHINE_FEATURES, let machine-sdk/ set it

There is actually a use for nativesdk MACHINE_FEATURES; for example
qemu-usermode being supported, as this is needed to build profile-guided
optimised code.

We shouldn't use the target MACHINE_FEATURES for this because the target
and the SDK can be entirely different, so instead set the
MACHINE_FEATURES in nativesdk.bbclass to SDK_MACHINE_FEATURES (which
defaults to "") and let the conf/machine-sdk/*.conf files set that as
appropriate.
