memstick: change to new flag variable

The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing
anything because this flag only has effect on sources at the same level
as the makefile (i.e., per directory). Since both core/ and host/ rely
on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the
appropriate choice.
