github: dist: Rework the automated functional tests

Now that Github Actions don't support cgroup v1, we can make the github
runners run the tests in a more granular fashion.  Add a runner to
individually run the containerized tests, the non-containerized tests,
and the sudo tests.  This simplifies the testing logic, and should help
us better identify failures.

As part of this, no longer run ftests-wrapper.sh when `make check` is
invoked on the ftests directory.  This is an undue burden for distros
as it requires uncommon dependencies (lxc, etc.) and can adversely
affect the cgroup sysfs filesystem on the build system.  The onus is
on upstream libcgroup to provide a well-tested and vetted *.tar.gz for
the distros that they can then just package up and disseminate.  They
shouldn't have to deal with challenging tests and test configurations.
