test_hash.c: refactor into kunit

Browse Source 
Use KUnit framework to make tests more easily integrable with CIs.  Even
though these tests are not yet properly written as unit tests this
change should help in debugging.

Also remove kernel messages (i.e.  through pr_info) as KUnit handles all
debugging output and let it handle module init and exit details.

Enable this option to test the kernel's string (<linux/stringhash.h>), and
integer (<linux/hash.h>) hash functions on boot.
KUnit tests run during boot and output the results to the debug log
in TAP format (https://testanything.org/). Only useful for kernel devs
running the KUnit test harness, and not intended for inclusion into a
production build.
For more information on KUnit and unit tests in general please refer
