Subject: [PATCH v3 4/6] crypto: testmgr - disallow plain cbcmac(aes) in FIPS mode

From: Nicolai Stange <[email protected]>

cbcmac(aes) may be used only as part of the ccm(aes) construction in FIPS
mode. Since commit d6097b8d5d55 ("crypto: api - allow algs only in specific
constructions in FIPS mode") there's support for using spawns which by
itself are marked as non-approved from approved template instantiations.
So simply mark plain cbcmac(aes) as non-approved in testmgr to block any
attempts of direct instantiations in FIPS mode.
