prog: introduce strict parsing mode

Over time we relaxed parsing to handle all kinds of invalid programs
(excessive/missing args, wrong types, etc).
This is useful when reading old programs from corpus.
But this is harmful for e.g. reading test inputs as they can become arbitrary outdated.
For runtests which creates additional problem of executing not
what is actually written in the test (or at least what author meant).
Add strict parsing mode that does not tolerate any errors.
For now it just checks excessive syscall arguments.
