runx: robustness changes

Adding one build and one runtime robustness change:

  - build: specify the syroot native as a library path to qemu user.
           This allows us to run dynamic executables

  - runtime: add a patch to increase the serial fd timeout. We'll
             drop this once it is merged upstream.

+Subject: [PATCH] runX: add bounded / looping timeout

+On slower machines, we may need a longer timeout before giving
+up.
