[Fuego] [PATCH] kselftest: add linux kernel selftests to fuego

[Daniel Sangorrin]

This test has a very similar format to kernel_build but it
skips the build of the whole kernel and only builds the tests.
The test is working for me in docker.

Next, I want to cover corner cases such as support for different
kernel versions, support for build/run only specs, and improve
the specs by adding more cases and separating tests that
need root privileges from those that do not.
