ColorfulRhino 82aa7b3963 compilation: armbian-kernel: Change forced uncompressed modules option for kernels >=v6.12
The kernel option `CONFIG_MODULE_COMPRESS_NONE`  was superseded by `CONFIG_MODULE_COMPRESS` in 6.12.
Adapt the kernel compilation script accordingly to force the correct kernel option.
