D1858: tests: make hg frame optional

[mharbison72 (Matt Harbison)]

  I haven't been paying attention to the rust threads, but is there an hghave test for it?  I don't see one locally.  If so, then all that should be needed is appending ' (no-rust !)'.  (Note the spaces.)  I think this works for #test-cases too.
  
  Note that this is *not* an "if and only if" test.  If you evaluate the feature(s) listed, it will be required for '(true !)', and reverts to (?) for '(false !)'.  I had a patch to make it IFF, because that's how it seems to be used in practice.  But somehow I came up with a test that succeeded outside test-run-tests.t, but failed inside it.
