olddefconfig only ran when .config was generated from the defconfig, so changes applied to an existing .config (e.g. with kconfig-tweak) never got their dependent defaults. Run olddefconfig on reconfigure as well, as the Make flow does on every build. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code

Summary
olddefconfig only ran when .config was generated from the defconfig, so changes applied to an existing .config (e.g. with kconfig-tweak) never got their dependent defaults. Run olddefconfig on reconfigure as well, as the Make flow does on every build.
Impact
align cmake with make
Testing
update cmake generated config with kconfig-tweak
