[OE-core] [PATCH] native/nativesdk: Ensure DISTRO_FEATURES is determistic

[Richard Purdie]

set() order is random and hence the filtered native/nativesdk DISTRO_FEATURES
could be set to random ordering. We've been lucky so far this tended not to
cause issues but some queued changes highedlighted this. Thrown in a sorted()
so the order is deterministic and we get consistent hash checksums between runs
and between machines.
