ci: disable algorithm support checking in softhsm

The algorithm support detection script doesn't seem to work when using
the SoftHSM module. For some reason, dnssec-keygen returns 'crypto
failure'. Since the tests themselves pass, this is likely to be some
bug/definiency in the test scripts that check algorithm support that get
confused by SoftHSM.

Since this issue only happens for the system:gcc:softhsm2.6 job in the
9.16 branch, use a workaround to not introduce this new feature for
this particular problematic job.
