ANDROID: fips140: add AES-CMAC

AES-CMAC is a FIPS allowed algorithm, and fips140.ko already has
arm64 implementations of it.  Meanwhile, GKI includes both these arm64
implementations as well as the "cmac" template.  Add the "cmac" template
to fips140.ko too and add a self-test for AES-CMAC, so that we can
include AES-CMAC in the set of algorithms which will be certified.

As with a number of the other algorithms, the criteria for which
algorithms need to be in the certified set are still not particularly
clear, but the latest guidance we've received is to error on the side of
including algorithms.
