lkl: set host memcpy/set/move defaults in Kconfig

Browse Source 
The LKL_HOST_MEMCPY, LKL_HOST_MEMSET and LKL_HOST_MEMMOVE kernel config
parameters are currently set via tools/lkl/Makefile.autoconf based on
whether OUTPUT_FORMAT starts with "elf64" or "elf32".
Use the same logic in arch/lkl/Kconfig to set the parameter defaults and
remove the corresponding Makefile.autoconf set_kernel_config calls.
