configs: use syntax CONFIG_FOO=n in tools-only_defconfig

The tools-only defconfig causes troubles on MacOSX due to the default
C compiler being Clang (LLVM) rather than GCC and more specifically
due to [1]. Therefore replace "# CONFIG_FOO is not set" with the
equivalent "CONFIG_FOO=n" using the following command:

 $ sed -i -e 's/# \(CONFIG_[^ ]*\) is not set/\1=n/' \
       configs/tools-only_defconfig

This fixes the tools_only_macOS CI job on GitHub [2].
