[v2,0/2] Fix KSFT toplevel makefile behaviour

Hi

so this series carries two small fixes to the toplevel KSelfTest makefile
which I found useful especially while attempting to run the suite in
automation.

[1/2]
While it is already possible to specify a limited list of TARGETS to run,
it is not instead easily possible to state a list of targets NOT to run
(say due to specific instability issues).
Moreover providing such a skip list through a stripped down list of TARGETS
it is cumbersome and fragile since this poses the risk to stick to an old
stale stripped TARGETS list once upstream decides to add more default
targets.
A new SKIP_TARGETS Makefile variable is provided by this patch to easily
specify a skiplist for target subsystems.

[2/2]
Currently when some target fails to build, KSFT Makefile just carries on
building as much subsystems as it can: unfortunately this is not properly
reflected also in the generation of the runlist inside run_kselftest.sh.
This patch rectifies this behaviour checking for the existence of a target
directory in the INSTALL_PATH before adding the related snippet to the
run_kselftest.sh script.


Thanks

Cristian
