[PATCH v2] scripts: kconfig: merge_config.sh: keep temp file in the output dir

merge_config.sh currently creates a temporary file in the current
directory. Create it under $OUTPUT instead, which allows running the
script against a read-only source tree.

The default behavior is unchanged: $OUTPUT is "." so the file stays in
the cwd.
