[PATCH] qemu.inc: depend on qemu-native only with runqemu DISTRO_FEATURE

[Martin Jansa <martin.jansa@gmail.com>]

* qemu images are usefull even without qemu installed on build machine.
  Some people are building on one machine, but then downloading images
  somewhere else to test them.
* use new "runqemu" DISTRO_FEATURE and BACKFILL it so the behavior stays
  the same, unless disabled by DISTRO_FEATURES_BACKFILL_CONSIDERED
