USB_DEBUGGING_ENABLED does not enable adbd

The following code has no effect because apparently ROOTFS_POSTPROCESS_COMMAND only works in image recipes

meta-openembedded/meta-oe/recipes-devtools/android-tools/android-tools_5.1.1.r37.bb

Line 190 in 6c2bd3c

    
           ROOTFS_POSTPROCESS_COMMAND_${PN}-adbd += "${@bb.utils.contains("USB_DEBUGGING_ENABLED", "1", "android_tools_enable_devmode;", "", d)}"

Hence, setting USB_DEBUGGING_ENABLED to "1" in local conf does not have the intended effect of enabling adbd.

Workaround is to add the same to your image recipe.
