    build: profiles.json: add kernel version information
    
    Currently downstream tools like ASU lack information about kernel
    version to find out the relevant kmod build folder on downloads server.
    
    So lets fix it by providing a new `linux_kernel` JSON array which would
    for the start provide Linux kernel version, revision and vermagic
    information.
    
      "linux_kernel": {
         "release": "1",
         "vermagic": "b57450c07d3a786158c3601fc5cee57d",
         "version": "6.6.61"
       },
    
    Fixes: openwrt/openwrt#17036
    Fixes: efahl/owut#9
