[PATCH 04/13] simfs: Quiet sanitizer runtime error

The arguments passed into memcpy for src and 'n' are NULL pointer and 0
respectively.  Strictly speaking null pointers should not be passed to
memcpy, and this raises a sanitizer runtime error:
src/simfs.c:1057:2: runtime error: null pointer passed as argument 2, which is declared to never be null

Use the newly introduced l_memcpy function to avoid triggering the
sanitizers
