[groff]: Revise a test to be more revealing.

* src/roff/groff/tests/initialization_is_quiet.sh: Stop using "set -e".
  Instead use `fail` variable and `wail` function (and lowercase names
  for our internal variables) like many of our other tests.  If the
  "unset" shell built-in fails, skip the test (prompted by
  /usr/xpg4/bin/sh on Solaris).  Attempt every groff locale, with and
  without compatibility mode initially enabled, instead of stopping at
  the first failure.  Report standard error and standard output content
  separately.  Use groff's `-a` flag to prepare the standard output, for
  readability.

* PROBLEMS: Document that this test might be skipped rather than failing
  on Solaris.  (What actually happens depends on which shell you run it
  with, and we advise a variety of approaches.)

Thanks to Bruno Haible for feedback regarding mysterious failures of
this test on GNU/Hurd and NetBSD systems.

     /usr/xpg4/bin/sh is non-conforming with the POSIX Issue 4 standard,
     despite its name.  Its "unset" builtin is buggy.
