Makefile: repair CONFIG_CC_OPTIMIZE_FOR_DEBUG support

Browse Source 
Since commit 5f520875bdf0 ("kbuild: Bump the build system to 5.1")
CONFIG_CC_OPTIMIZE_FOR_DEBUG has no effect on the non-host code.

This patch reestablishes the prior logic to add

    -Og -Wno-maybe-uninitialized

to KBUILD_CFLAGS.
