[PATCH 3/6] notes: don't leak memory in git_config_get_notes_strategy

[Stefan Beller <sbeller@google.com>]

`value` is just a temporary scratchpad, so we need to make sure it doesn't
leak. It is xstrdup'd in `git_config_get_string_const` and
`parse_notes_merge_strategy` just compares the string against predefined
values, so no need to keep it around longer.
