Public bug reported:

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
flach (not usin 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.
