samples/bpf: Add include dir for MIPS Loongson64 to fix build errors
There exists many build errors when make M=samples/bpf on the Loongson platform. This issue is MIPS related, x86 compiles just fine. Here are some errors: CLANG-bpf samples/bpf/sockex2_kern.o In file included from samples/bpf/sockex2_kern.c:2: In file included from ./include/uapi/linux/in.h:24: In file included from ./include/linux/socket.h:8: In file included from ./include/linux/uio.h:8: In file included from ./include/linux/kernel.h:11: In file included from ./include/linux/bitops.h:32: In file included from ./arch/mips/include/asm/bitops.h:19: In file included from ./arch/mips/include/asm/barrier.h:11: ./arch/mips/include/asm/addrspace.h:13:10: fatal error: 'spaces.h' file not found ^~~~~~~~~~ 1 error generated.
