suite initialization failure is not handled by parser

[teacup-on-rockingchair]

parser of cunit output does not handle suite initialization failure, in case programmer does not take care to report error exit code in that case.
The Cunit generally outputs following message:
WARNING - Suite initialization failed for ....
and in the summary one can see that we have suites that are not run. For example:

[#] Run Summary: Type Total Ran Passed Failed Inactive
[#] suites 3 2 n/a 1 0
[#] tests 26 24 24 0 0
[#] asserts 185 185 185 0 n/a
