hello-2.1.91: no skip test

[Bruno Haible]

Hi,

I think GNU hello should also show how to deal with skipped tests.
  1) to learn about the magic code 77,
  2) to print a reason why the test is skipped. (I did this wrong in GNU
     gettext for years. When I added such an explanation message to all
     skipped tests, I discovered a few bugs.)

Here is a test that
  - is skipped most of the time,
  - still does something useful,
  - does not require new features to be added to the hello program.

The new test file should be subject to "chmod a+x" before "cvs commit".
