[RFC v8 18/20] selftests/um: lkl: add test programs for library mode of UML

Add a simple LKL test application (boot) that starts the kernel and performs simple tests that minimally exercise the LKL API. The tests are implemented on kselftest framework, which can be invoked with

make ARCH=um SUBARCH=lkl TARGETS="um" kselftest

Additionally, this commits add a skip for headers_install for ARCH=um since UML (even with library mode) doesn't have headers install.

``` cat /tmp/um-test.tap | sed "s/^# selftests/ # Subtest: selftests/" | sed "s/^#/ /" | sed "s/version 13/version 14/" | sed "s/(ok [0-9]* )/\1- /" | ./tools/testing/kunit/kunit.py parse ```

this makes tap14 converter for the kselftest results.
