[Buildroot] [PATCH] kconfig: support read-only Buildroot source directories

merge_config.sh currently tries to create a .tmp file in the top-level
Buildroot source tree. This fails when that directory is read-only, leading
to unexpected .config file contents (affecting the configuration of Buildroot
itself, Linux, and Busybox).
Fix it by using mktemp --tmpdir to create the .tmp file in $TMPDIR or /tmp.
