build: add git describe info as modinfo

For traceability purposes, we include commit descriptions as MODULE_VERSION information in drivers that are deployed in CERN control system. Ideally, the commit description should be added to all the binary blobs installed, but the kernel module is critical in this connection, as it is crucial to trace back quickly the whereabouts of installed .ko sources.
