[PATCH i-g-t 1/1] scripts/test_list: relax treatment of non-compiled tests

[Kamil Konieczny <kamil.konieczny@linux.intel.com>]

Some tests could be added and compiled only when non-default
meson option is given. It will result in no testlist generated
for such tests but they could appear in our documentation.
Currently we report an error in such case.

Create a way to detect and report that and treat this as feature
and do not report it as an error.  This should allow to relax
processing of chamelium and other new tests.

Also while at this, print error information before actually
exiting with an error code, as previous prints were only
warnings.
