Update README.FIPS for new FIPS 2.0 testvectors.

To build the module do:

./config fipscanisterbuild

./config fipscanisteronly

make

Build should complete without errors.

Run test vectors: 

1. Download an appropriate set of testvectors from www.openssl.org/docs/fips

   those for 2007 are OK.

   only the fips-2.0 testvector files are usable for complete tests.

2. Extract the files to a suitable directory.

3. Run the test vector perl script, for example:

   cd fips

   perl fipsalgtest.pl --disable-v2 --dir=/wherever/stuff/was/extracted

   perl fipsalgtest.pl --dir=/wherever/stuff/was/extracted

4. It should say "passed all tests" at the end. Report full details of any

   failures.

If you wish to use the older 1.2.x testvectors (for example those from 2007)

you need the command line switch --disable-v2 to fipsalgtest.pl

Examine the external symbols in fips/fipscanister.o they should all begin

with FIPS or fips. One way to check with GNU nm is:

Known issues:

Algorithm tests are pre-2011.

The fipslagtest.pl script wont auto run new algorithm tests such as DSA2.

Code needs extensively reviewing to ensure it builds correctly on 

supported platforms and is compliant with FIPS 140-2.

The "FIPS capable OpenSSL" is still largely untested, it builds and runs
