Title:
  android container should not enable adb and mtp from default.prop

Bug description:
  if the android container rootfs is built with ro.debuggable=1 it will
  put a default.prop file into the container rootfs with
  persist.sys.usb.config set to mtp,adb. on first boot after a factory
  flash (not using ubuntu-device-flash) when there was no value for this
  property set prior to starting the container this causes the gadget to
  be in adb mode without running adbd daemon. in his case the device
  will show up as "offline" in "adb devices" on a PC until developer
  mode was toggled once in the settings UI.

  lxc-android-config needs to ship a pre-start.d snippet that removes
  this entry from default.prop. this way recovery boots can still
  benefit from ro.debuggable being set while adb behavior will not be
  affected in normal boots.

  #! /bin/sh

  sed -i '/^persist.sys.usb.config=.*/d' $LXC_ROOTFS_PATH/default.prop
