fix issue with non-ascii characters in path

Path to SublimeLinter has Cyrilic symbols, SublimeLinter works but console print is:
```python
Writing file /C/Users/Кирилица однако/AppData/Roaming/Sublime Text 2/Packages/SublimeLinter/SublimeLinter.py with encoding UTF-8
Traceback (most recent call last):
  File ".\sublime_plugin.py", line 190, in on_post_save
  File ".\sublime_plugin.py", line 154, in run_timed_function

  File ".\SublimeLinter.py", line 610, in reload_view_module
UnicodeDecodeError: 'ascii' codec can't decode byte 0xcc in position 9: ordinal not in range(128)
```

I've changed 'utf-8' encoding to `sys.getfilesystemencoding();`
`module.__file__` is 'str' and there is no need to encode;
