rG12a6257a9600: sys/conf: Introduce NOSAN_CFLAGS and NOSAN_C
Summary

To simplify disabling the kernel sanitizers in some files add
NOSAN_CFLAGS and NOSAN_C variables. These are CFLAGS and NORMAL_C with
the sanitizer flags removed.

While here add MSAN_CFLAGS to simplify keeping KMSAN in kern_kcov.c

Fix the module build. NOSAN_CFLAGS was wrong when used in kmod.mk

Does it not work to define these in kern.mk instead of here and in kmod.mk?
