ANDROID: fips140: add fips140_lab_util program

Add a sample program that supports various tests that the FIPS
certification lab is required to do on fips140.ko.  To do its work it
uses AF_ALG, as well as the /dev/fips140 device node provided by a build
of fips140.ko with CONFIG_CRYPTO_FIPS140_MOD_EVAL_TESTING enabled.
