Split table list returned by _drush_sql_get_db_table_list() correctly when on windows.

Exploding the newline-seperated string of table names only on newline characters (\n) leaves all corresponding carriage return (\r) chars behind. confusing all checks performed directly on the array, such as in_array. As e.g "sessions" != "sessions\r", $skip_tables oder $structure_tables will only contain the respective setting's last element.
