mm/kasan: Fix compile options applied to wrong target in SPLIT build

Browse source 
In SPLIT build mode, nuttx_add_kernel_library(mm SPLIT) creates two
targets: mm (system library) and kmm (kernel library). The compile
options were being applied to the mm target via
target_compile_options(mm ...), but the kasan instrumentation is
compiled as part of the kmm target.

Change target_compile_options(mm ...) to target_compile_options(kmm
...) so that FLAGS (including -fno-builtin and NO_LTO) are correctly
applied to the kernel target where kasan code is compiled.
