The Makefile wasn't in the appropriate format for DKMS. While it did
work on the Coral Dev Board, it failed on other devices.
Tested:
Coral Dev Board, x86 Debian Machine
* The Makefile configuration was using kernel macros instead of obj-m,
so it wasn't building properly.
* Bump gasket and apex module versions for better DKMS installs.
* Bump Debian package version.
