Disable cli/args test for now, but continue testing roc check on it

Args.roc has always been in a broken state, relying on particular
hand-holding of the compiler to operate. With recent changes to type
emplacement, Args.roc now shows off compiler bugs that cannot be papered
over and need to be addressed head-on. These are problems that I do not
think can be directly solved via eliminating type emplacement; I think
they are a combination of constraining and mono bugs, and will be
investigated separately.

For now, turn off attempts to build Args, and instead just test that
`roc check` continues to behave well.
