kernel: Stop using update-alternatives

The update-alternatives where using relative links so not being really
in use since December 2016 (see OE-Core:c7bc46b9 "kernel: Fix
symlinks") so instead we now generate the relative symlinks during the
do_install task and drop the update-alternatives use at all.
