AndroidKernelModule.mk: sync the file with qcom dlkm

Browse source 
fix the compile error during GKI kernel 5.4:
FAILED: ninja: 'out/target/product/jordan/dlkm/lib/modules/gki/utags.ko', needed by 'out/target/product/jordan/vendor/lib/modules/5.4-gki/utags.ko', missing and no known rule to make it

When build user variant, Qcom will build all kernel and modules with both
GKI and QGKI kernel configs, so Moto kernel modules should use the qcom's
latest dlkm's AndroidKernelModule.mk
