Logging issues

[secretsquirrel]

On master I get a ton of logging errors. These errors keep important data from making into the .json output. Imagine this, but hundreds of times.

[ERROR]   <type 'exceptions.IOError'> [('./osxcollector.py', 1009, '_log_file_info_for_directory', 'file_info = _get_file_info(file_path, True)'), ('./osxcollector.py', 312, '_get_file_info', 'where_from = _get_where_froms(file_path)'), ('./osxcollector.py', 243, '_get_where_froms', 'return _get_extended_attr(file_path, ATTR_KMD_ITEM_WHERE_FROMS)'), ('./osxcollector.py', 262, '_get_extended_attr', 'xattr_val = getxattr(file_path, attr)'), ('/usr/local/lib/python2.7/site-packages/xattr/__init__.py', 178, 'getxattr', 'return xattr(f).get(attr, options=symlink and XATTR_NOFOLLOW or 0)'), ('/usr/local/lib/python2.7/site-packages/xattr/__init__.py', 68, 'get', 'return self._call(_getxattr, _fgetxattr, name, 0, 0, options | self.options)'), ('/usr/local/lib/python2.7/site-packages/xattr/__init__.py', 59, '_call', 'return name_func(self.value, *args)'), ('/usr/local/lib/python2.7/site-packages/xattr/lib.py', 642, '_getxattr', 'raise error(path)'), ('/usr/local/lib/python2.7/site-packages/xattr/lib.py', 628, 'error', 'raise IOError(errno, strerror, path)')] - {'osxcollector_incident_id': 'osxcollect-2015_12_19-15_57_57', 'osxcollector_username': 'yourmom', 'osxcollector_section': 'mail'}`

Repro:

sudo ./osxcollector.py

It seems that the issue is caused by xattr.getxattr throwing IOError instead of KeyError when the attribute is not found.
I will add a second except section to the try/except block in order to ignore IOError.

Closed in #124.
