[PATCH liburing v1 1/2] tests: fix bpf ops build error

[Haiyue Wang]

If removed the previous install by 'rm -rf /usr/include/liburing', the
test build will fail:

make[1]: Entering directory '/root/linux/liburing/test'
     CC helpers.o
mkdir -p output/bpf
     CC output/bpf/nops.bpf.o
mkdir -p output/bpf
     CC output/bpf/cp.bpf.o

Add the include option in 'CPPFLAGS' for bpf build.
