configs/hardening: Fix disabling UBSAN configurations
The initial change that added kernel/configs/hardening.config attempted
to disable all UBSAN sanitizers except for the array bounds one while
turning on UBSAN_TRAP. Unfortunately, it only got the syntax for
CONFIG_UBSAN_SHIFT correct, so configurations that are on by default
with CONFIG_UBSAN=y such as CONFIG_UBSAN_{BOOL,ENUM} do not get disabled
properly.
CONFIG_ARCH_HAS_UBSAN=y
CONFIG_UBSAN=y
CONFIG_UBSAN_TRAP=y
CONFIG_CC_HAS_UBSAN_BOUNDS_STRICT=y
CONFIG_UBSAN_BOUNDS=y
CONFIG_UBSAN_BOUNDS_STRICT=y
# CONFIG_UBSAN_SHIFT is not set
# CONFIG_UBSAN_DIV_ZERO is not set
# CONFIG_UBSAN_UNREACHABLE is not set
CONFIG_UBSAN_SIGNED_WRAP=y
CONFIG_UBSAN_BOOL=y
CONFIG_UBSAN_ENUM=y
# CONFIG_TEST_UBSAN is not set
Add the missing 'is not set' to each configuration that needs it so that
they get disabled as intended.
CONFIG_ARCH_HAS_UBSAN=y
CONFIG_UBSAN=y
CONFIG_UBSAN_TRAP=y
CONFIG_CC_HAS_UBSAN_BOUNDS_STRICT=y

# CONFIG_UBSAN_SHIFT is not set

# CONFIG_UBSAN_UNREACHABLE is not set
