apps: cover the gendsa error cases and verbose mode in the test recipe

Cover the bad option failures (missing and extra arguments, unknown
cipher and invalid password argument) as well as the failures when
loading a nonexistent, invalid or non-DSA parameters file, verifying
the error messages printed to stderr.  Also extend the -verbose test
to check the reported progress output and cover the -quiet option.
