ANDROID: fips140: refactor evaluation testing support

It turns out that we have to add more code to the module to support lab
evaluation testing, beyond the error injection support we currently
have.  Therefore, rename CONFIG_CRYPTO_FIPS140_MOD_ERROR_INJECTION to
CONFIG_CRYPTO_FIPS140_MOD_EVAL_TESTING, and move the relevant code into
a new file fips140-eval-testing.c which is conditionally compiled.

Also rename the "broken_alg" module parameter to "fail_selftest" so that
it is similar to "fail_integrity_check" which we'll be adding.
