ci: Enable experimental kernel stuff in valgrind task

Base the task on --preset=dev-mode to ensure maximal coverage and add
the following:

   bitcoin-chainstate (experimental) ... ON
   libbitcoinkernel (experimental) ..... ON
   kernel-test (experimental) .......... ON

The GUI and USDT remain disabled explicitly.
