Regarding to packet03-redirecting, added common_user_bpf_xdp.o to COMMON_OBJS.
In packet03-redirecting/xdp_prog_user.c, common/common_user_bpf_xdp.h is included, but common_user_bpf_xdp.o is not included in COMMON_OBJS. This omission causes the build to fail during assignment3, as open_bpf_map_file() cannot be referenced.
