  Issue #8603: Create a bytes version of os.environ for Unix

  Create os.environb mapping and os.getenvb() function, os.unsetenv() encodes str
  argument to the file system encoding with the surrogateescape error handler
  (instead of utf8/strict) and accepts bytes, and posix.environ keys and values
  are bytes.
