pkg-cmake.mk: globally drive the CMAKE_BUILD_TYPE flag using BR2_ENABLE_DEBUG
This CMake flag is usually used to adjust compiler flags (like: -Ox, -g,
etc).
So, it makes sense for Buildroot to globally drive this CMake flags in
the cmake-package infrastructure.
However, if a package prefer overriding this default setting, it still
can via the <PKG>_CONF_OPT variable.
