Use soong namespace to branch a implementation of insmod.sh . The newly added implementation is only added to PRODUCT_PACKAGE for dev option enabled devices. The only change to the script is skip loading kernel modules from vendor|system_dlkm when under 16K mode. Test: Dev option works Bug: 319335586 Change-Id: Ice77c19cad47f299db113f11878182f37e0b6f91
