perf bpf skels: Make vmlinux.h use bpf.h and perf_event.h in source directory
Currently, vmlinux.h uses the bpf.h and perf_event.h header files in the
system path. If the header files in compilation environment are old,
compilation may fail. For example:
/home/yangjihong/linux/tools/perf/util/bpf_skel/.tmp/../vmlinux.h:151:27: error: field has incomplete type 'union perf_sample_weight'
union perf_sample_weight weight;
Use the bpf.h and perf_event.h files in the source code directory to
avoid compilation compatibility problems.
