Makefile: ensure utils/ exists before writing to it

Since utils/ was changed to not build recursively it's possible that in
out-of-tree builds the utils/ directory hasn't been created when Make runs the
utils/kconfig-tweak target which tries to write to file inside utils/.

This is the case, for example, when using --disable-dependency-tracking.

To ensure this can work, mkdir the directory.
