Update 'abort_not_supported_test' to print a reason why the test was aborted

and use it in mysql-test-run.pl
Use standard defines as last argument to 'fn_format'

  Rename: mysql-test/r/true.require -> mysql-test/r/not_ndb_default.require

  Use proper defines for last argument to fn_format(they are defined in my_sys.h)
  Make abort_not_supported_test print info about in what file the test was 
  aborted and a reason for it. The reason is a best guess, using the filename of
  the .require file to format it.

  Use a more descriptive name of the .require file
mysql-test/include/not_windows.inc:
