  Fix test_undecodable_env of test_subproces for non-ASCII directory

  This test was introduced by r80421 (issue #8391).

  The fix: copy the environment variables instead of starting Python in an empty
  environement. In an empty environment, the locale is C and Python uses ASCII
  for the default file system encoding. The non-ASCII directory will be encoded
  using surrogates, but Python3 is unable to load a module or package with a
  filename using surrogates.

  See issue #8242 for more information about running Python3 with a non-ascii
  directory in an empty environement.
