ANDROID: fips140 - add option for debugging the integrity check

There now have been two times where I've had to debug the fips140
integrity check failing due to a new type of runtime code patching.
Debugging such issues requires dumping the text and rodata actually used
for the integrity check and comparing them with the originals.  Add a
kconfig option to make this easier.  Similar to
CRYPTO_FIPS140_MOD_EVAL_TESTING, the production build won't use this.
