ANDROID: fips140: fix the error injection module parameters

Browse Source 
Commit 63f46b45dda2 ("ANDROID: fips140: eliminate crypto-fips.a build
step") made all fips140 source files other than fips140-module.c be
compiled in the "fake built-in code" mode.  This broke the fail_selftest
and fail_integrity_check module parameters, as they are defined in
fips140-eval-testing.c.  Fix this by making fips140-eval-testing.c be
compiled "normally", overriding fips140-defs.h.
