Cleanup of --minimal-modules tests

Fixed some issues in my new --minimal modules tests that I didn't
get the first time around:

* disabled the test for CHPL_COMM == gasnet.  I tested that my mods
  didn't break GASNet, but didn't check to see whether or not the new
  tests would work under GASnet.  They don't currently.  With
  additional work, they potentially could, though how much more module
  code would have to be brought over would need to be considered.

* disabled the test for --baseline as well.  It fails in this case due
  to an attempt to codegen dtUnknown.  I'm not sure why and am not
  sure it's worth fixing at this point, so am skipping instead.

* rewrote the tests to improve portability [reviewed in spirit by
  Kyle]: I'd been using %ld to print out a default int in Chapel but
  clang requires it to be %lld to avoid warnings.  The right format
  string to use for safety/portability is "%" PRId64, but this is not
  supported by Chapel (TODO: We should come up with some sort of
  wrapper for these maybe?  Or would that just encourage proliferation
  of printf()s beyond what we'd want?).  So instead, I dialed the int
  variables down to 8-bit ints which should make them safe to print
  with "%d" according to C rules as I understand them (and testing
  shows that it works on clang and linux).
