[PATCH 18/21] builtin/config: convert `key` to a local variable
From: Patrick Steinhardt <hidden>

The `key` variable is used by the `get_value()` function for two
purposes:
- It is used to store the result of `git_config_parse_key()`, which si
then passed on to `collect_config()`.
- It is used as a store to convert the provided key to an
all-lowercase key when `use_key_regexp` is set.
Both of these cases don't warrant a global variable at all. In the
former case we can pass the key via `struct collect_config_data`. And in
the latter case we really only want to have it as a temporary local
variable such that we can free associated memory.
Refactor the code accordingly to reduce our reliance on global state.
