AOSCOS: MIPS: lib: exclude generic memset.o if CPU_LOONGSON64 is set

In "AOSCOS: memset optimization for loongson-3", a Loongson-3-specific
memset implementation was introduced, with its own set of definitions
for `bzero' and `memset' routines. This resulted in multiple definitions
for the aforementioned assembly routines, causing vmlinux to fail to link.

Exclude generic memset.o if `CPU_LOONGSON64' is set to avoid this error.
