Subject: [PATCH] [Fix] Error: util/configlexer.c: No such file or directory

The error happens because a recent code contribution removed the generated lexer and parser files from the code repository. With installed flex and bison, the files are created during the compile.
Thanks to [@wcawijngaards](https://github.com/wcawijngaards) for the fix explained [here](https://github.com/NLnetLabs/unbound/issues/885#issuecomment-1534391750)
