Subject: [PATCH] build: profiles.json: add kernel version information
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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
