cmake: Make BUILD_KERNEL_TEST depend on BUILD_KERNEL_LIB #33972

   The CMake script in the test/kernel subdirectory is already gated by BUILD_KERNEL_LIB:https://github.com/bitcoin/bitcoin/blob/f6acbef1084e34f126bf530df99e4ef6a11c38e8/src/CMakeLists.txt#L405-L409

   As a result, the following configuration summary is misleading:

   0$ cmake -B build -DBUILD_KERNEL_LIB=OFF -DBUILD_KERNEL_TEST=ON
   1<snip>
   2  bitcoin-chainstate (experimental) ... OFF
   3  libbitcoinkernel (experimental) ..... OFF
   4  kernel-test (experimental) .......... ON
   5<snip>
   

   This PR fixes the behaviour by making the BUILD_KERNEL_TEST option explicitly depend on BUILD_KERNEL_LIB.
