Andrea Righi c730e0558f ci: test the shedulers with the latest sched-ext kernel
Instead of downloading a precompiled sched-ext enabled kernel from the
Ubuntu ppa, fetch the latest kernel directly from the sched-ext git
repository and recompile it on-the-fly using virtme-ng.

This allows to get rid of the Ubuntu ppa dependency, take out from the
equation potential Ubuntu-specific patches, and ensures testing all the
schedulers with the most up-to-date sched-ext kernel (that should also
help to detect potential kernel-related issues in advance).

The downside is that the CI runs will take a bit longer now, because we
are recompiling the kernel from scratch. However, the kernel built with
virtme-ng is relatively quick to compile and includes all the sched-ext
features required for testing.

It's worth noting that this method aligns with the current sched-ext
kernel CI, where we test only the in-kernel schedulers (as intended).

This change allows to extend the test coverage, using the same kernel to
test also the schedulers included in this repository.
