builtin/config: convert regexp to a local variable

The `regexp` variable is used by the `format_config()` callback when
`CONFIG_FLAGS_FIXED_VALUE` is not set. It is only ever set up by its
only caller, `collect_config()` and can thus easily be moved into the
`collect_config_data` structure.

Do so to remove our reliance on global state.
