examples/fips_validation: fix parsing of TDES vectors

Processing of test vector for COUNT = 0 is getting skipped, as
some of the NIST TDES files doesn't have an empty line after
[ENCRYPT]/[DECRYPT] and thus treated as an interim block.

Parse function now identifies such blocks, separates out interim
and test vector data, and then parses each with their respective
callbacks.
