Catch EC_R_UNKNOWN_GROUP in check_unsupported()
If EC support is enabled we should catch also EC_R_UNKNOWN_GROUP as an hint to
an unsupported algorithm/curve (e.g. if binary EC support is disabled).
Before this commit the issue arise for example if binary EC keys are added in
evptests.txt, and the test is run when EC is enabled but EC2m is disabled.
E.g. adding these lines to evptests.txt would reproduce the issue:
