chore(vvenc): comment out configuration and unconfiguration echo statements

* Commented out the `echo --enable-libvvenc` in `ffbuild_configure`.
* Commented out the conditional check and `echo --disable-libvvenc` in `ffbuild_unconfigure`.
* These changes prevent unnecessary output during the build process.
