Fix a memory leak in t/helper/test-parse-options.c, we were not freeing the allocated "struct string_list" or its items. While I'm at it move the declaration of the "list" string_list the cmd__parse_options() function.
In c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09) the "list" variable was added, and later on in c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09) the "expect" was added.
The "list" variable was last touched in 2721ce21e43 (use string_list initializer consistently, 2016-06-13), but it was still left at the static scope, it's better to move it to the function for consistency.
