    kernel: kmod-can: Fix build of can drivers
    
    Many can kernel modules are now gated by the newly introduced
    CONFIG_CAN_NETLINK configuration option. Activate it to build the can
    drivers again.
    This was changed in this upstream Linux commit:
    https://git.kernel.org/linus/df6ad5dd838e0fa543ca28ca6154901fa65a9443
    
    This should fix these warnings with kernel 6.1 and 6.6:
    logs/package/kernel/linux/compile.txt:WARNING: kmod-can-c-can is not available in the kernel config - generating empty package
    logs/package/kernel/linux/compile.txt:WARNING: kmod-can-c-can-pci is not available in the kernel config - generating empty package
