APPS: ecparam: Support setting properties

APPS: ecparam: Support setting properties

The -provider and -propquery options did not work on ecparam. Fix this
and add tests that check that operations that would usually fail with
the FIPS provider work when run with

| -provider default -propquery '?fips!=yes'

fixed the same problem in dsaparam and gendsa. See also the initial
